Membergroup (term) From Online Manual
Every member of a forum belongs to a membergroup. A membergroup consists of members that you pick the members to be a part of and you choose the permissions allowed to the membergroup.
There are two types of membergroups:
- Post-Count based membergroup - Where the member's post count determines the membergroup into which the member is placed.
- Non-post count based membergroup - Where the members group determines the permissions and boards visible.
