Help From Online Manual
The help page located on the Main menu has a lot of similarities with the Using SMF As a Regular User section on this Wiki. But conveniently, admins won't have to send their members here since the members can find help getting around SMF straight from the forum they are viewing. They will find a lot of handy guidance about getting around SMF as a user and how to understand how to use the features of SMF.
The biggest difference between the help section found on the standard SMF powered forum is it is more interactive and user-friendly. Users will find by clicking on links, they will be lead to examples on how to accomplish certain things in a similar way as it is actually presented on an SMF forum.
Although the documentation here is more specific in some cases, most notably the extensive profile, being completely documented here.
