Introduction
Permissions are a very powerful tool for managing your forum. It is advisable to only change one permission at a time and to test it prior to changing another one. The reason is because the permissions can often interact with each other in unexpected ways, resulting in untested changes having unintended consequences. If you need help beyond the information provided on this page, please feel free to investigate other support options, which are found on this page: https://support.simplemachines.org/.
There are 2 separate sets of permissions. While these permission sets do not overlap, they certainly can interact, depending on how they are used. All permissions are given to people, or website visitors, and managed using membergroups. But these two sets are allocated and utilized differently.
- The General Permissions are applied to membergroups. So for example, you can give those people who belong to certain groups the ability to do things which those in other groups can't. Permissions can be applied to custom membergroups just the same as the original membergroups.
- The Board Permissions are also applied to membergroups. But these permissions are managed using profiles, one of which is assigned to each board. So for example, you can allow people or membergroups to have certain pemissions on one board, but not on another. There are four profiles and you can create custom profiles as well.
In the Admin Center > Members > Permissions sub-menu, there are 5 tabs: General Permissions, Board Permissions, Edit Profiles, Post Moderation, and Settings.
General Permissions
As mentioned above, General Permissions apply to people in membergroups, whether they are the original membergroups or custom groups.
This page shows a table which lists of all membergroups, along with a few statistics. If you have not yet added any custom membergroups, you will see 5 membergroups: Guests, Regular Members, Administrators, Global Moderators, and Moderators. Use the question mark icon on the left to find a definition for each group.
On the right side of the table, beside each membergroup, is a checkbox and a Modify text link. The Modify link allows the administrator to change specific permissions individually. The checkbox allows the administrator to apply the advanced options, which is a way to edit the entire membergroup at once.
Modify
Use the Modify text link to the right of each membergroup name to individually set one or more permissions for the members of this group. The top half of the page offers settings for the General Permissions which are explained in detail below. Please see the page, Moderator for more information on how the Moderator membergroup works. These will help you understand and decide how to set permissions. (The bottom half of the page shows the Board Permissions, which are explained even further below. They are included here with General Permissions for convenience. But they also appear on Board Permissions page.)
Advanced Options
These options allow you to make changes to the whole membergroup at once, using pre-defined permission sets. These are simply sets of permissions which provide generalized types of abilities. To use them, first select one or more membergroups from the table above, by checking the box on the same line with the membergroup name. Then make your choices in the With selection box below the table.
- Apply pre-defined permission set - Choose one of the four options from the dropdown menu: Restrictive, Standard, Moderator, or Maintenance. The question mark button to the left of each option explains the generalized types of permissions which each option provides.
- Set permissions like this group - Choose which group has the permissions closest to what you want for this membergroup.
- (Select a permission) dropdown menu offers all the available permissions which you might want to customize. Make your choice or choices.
- Add permission dropdown menu offers add permission and clear permission. If you have configured the Deny Permissions option on Members > Permissions > Settings, you will also have the Deny permission option to choose from. Thus you can decide whether you want your chosen membergroup to have each permission, not have it, or have it denied. (See further below more information about Deny Permissions.)
When you have completed your selections, click the Set permissions button to finalize each membergroup's permissions.

Board Permissions
As mentioned above, Board Permissions are also applied to membergroups. But they are managed with profiles, one of which is applied to each board. With these profiles, an admin could allow users to have permissions on one board that the same users might not have on another board. Combine these Board Permissions with the General Permissions, and you can begin to see how complex this feature can be!
These are the four profiles which are written into the program, but admins can also create their own custom profiles.
- Default - Initially this is a configuration which developers set up for general use, on all boards. It can be customized or even replaced with a different profile.
- No Polls - In boards with this profile, users can neither create nor participate in polls. This profile cannot be directly edited or customized. But you can create a new profile based on this one, and customize it.
- Reply Only - In boards with this profile, users cannot start new topics, but they can only reply to them. This profile cannot be directly edited or customized. But you can create a new profile based on this one, and customize it.
- Read Only - In these boards, users can only read, but not participate in topics. This profile cannot be directly edited or customized. But you can create a new profile based on this one, and customize it.
Change a Board's Profile
On the Board Permissions page, you can see a table which lists all the boards in your forum, along with the profile assigned to each board. To switch to a different profile on a particular board, click on the name of the board. On the next page, find the Permission Profile option and choose another profile from the dropdown menu. Then at the bottom of the page, click Modify button. When you get back to Board Permissions page, you'll see the new profile listed for that board.
Before moving on to editing the board permission profiles, below is the list of all the individual Board Permissions. These will help you understand and decide how to configure new profiles.

Edit Profiles
This page provides ways to create new permission profiles and edit, delete, or rename existing profiles.
Edit Profiles
All the existing permission profiles are listed along with the number of boards using each profile. To modify any existing profile, click on its name. You will then be taken to a page that lists the membergroups and the permissions they have been assigned in relation to this particular permission profile. To change the permissions of a membergroup within this permission profile, click on "Modify" next to the name of the membergroup.
New Profile
- Profile Name - In this box you can define the name of the new permission profile.
- Copy Permissions From - By selecting one of the existing profiles from this dropdown box, the permissions from this profile will be used for the newly created one.
Rename
You can rename permission profiles that you have created, but the four default permission profiles (Default, No Polls, Reply Only, and Read Only) cannot be renamed. When the Rename button is clicked, all the profiles you have created can be renamed, as long as they are not currently assigned to a board. After renaming a profile, make sure that you click on the Save Changes button.
Remove Selected
You can delete any permission profile that you have created. The four default permission profiles (Default, No Polls, Reply Only, and Read Only) cannot be removed. Select the checkbox on the same line as the profile you wish to remove, and then click the Remove Selected button. Note that you can only delete a permission profile if it is not currently assigned to a board.
Post Moderation
Post moderation must be enabled in Core Features for this page to be visible.
In this section admins can define the actions that require Post Moderation for each permission profile. This is a shortcut way of changing some of the permissions in the board permission profiles.
The administrator must first select a profile from the option list and select the go button. For each listed profile, there are four user actions for which post moderation permissions can be set. Each one corresponds to board permissions in the corresponding profile. For each of these user actions, three post moderation options are available.
- Can Create. The members can perform the action without moderation.
- Can Create but Requires Approval. The members can perform the action, but approval is required before becoming visible to all other members.
- Cannot Create. The member cannot perform the action.
| User Action | 
|
|
|
|---|---|---|---|
| New Topics | Post new topics, without requiring approval | Post new topics, but hide until approved | (neither allowed) |
| Own Replies | Post replies to topics, without requiring approval, own topic | Post replies to topics, but hide until approved, own topic | (neither allowed) |
| Any Replies | Post replies to topics, without requiring approval, any topic | Post replies to topics, but hide until approved, any topic | (neither allowed) |
| Attachments | Post attachments, without requiring approval | Post attachments, but hide until approved | (neither allowed) |
Post moderation cannot be used to set deny permissions even if deny is enabled. The 'cannot create' option in post moderation is only ever disallow.
Settings
- Membergroups allowed to manage permissions - Administrators can select which membergroups are allowed to manage permissions.
- Enable the option to deny permissions - Once enabled along with granting permissions it will be possible also to deny any permission. Denied permissions are not allowed even if the member belong to another membergroup for which the permission is granted.
- Enable permissions for post count based groups - Determines whether or not membergroups based on post count can be used to manage permissions.
About Permissions
Options
SMF's permissions are so powerful because they can be set for each individual permission to three options rather than just on or off.
- A - This option gives user current permission
- X - This option does not give the user current permission
- D - This option denies the user current permission
Things get really interesting when a user belongs to 2 or more membergroups with different options (A, X or D) for the same permission.
Member belongs to 2 membergroups
In this example a member belongs to only 2 different membergroups with different options for some permissions:
| permissions | option from group A | option from group B | Result for permission | explanation |
|---|---|---|---|---|
| permission 1 | A | A | allowed | obviously |
| permission 2 | A | X | allowed | A beats X |
| permission 3 | A | D | not allowed | D beats A |
| permission 4 | X | X | not allowed | obvious too |
| permission 2 | X | D | not allowed | D beats X |
| permission 3 | D | D | not allowed | is this obvious or what? |
In short: D beats A which beats X
Member belongs to 3 or more membergroups
- If you want a permission to be allowed, then you must have option A in at least one group and no D.
- If you want a permission to be disallowed, then you must have all options X, or
- If you want a permission to be disallowed, you must have option D in at least one group. It does not matter if other options are A or X.
You should not use D too much. Its a good idea to use special private membergroups just to Deny some permissions. If you don't want some members to use e.g. private messages, you can set up a private membergroup with a descriptive name like "no-pm" and for that membergroup, set the permissions for pm to D. Every member of that group is not allowed pm's regardless of the other groups they belong. If you change your mind about that setting you can find easily which membergroup restricts PMs and reset it.
