What are Usergroups?
Usergroups are a way in which board administrators can group users. Each user can belong to several groups (this differs from most other boards) and each group can be assigned individual access rights. This makes it easy for administrators to set up several users as moderators of a forum, or to give them access to a private forum, etc.
How do I join a Usergroup?
To join a usergroup click the usergroup link on the page header (dependent on template design) and you can then view all usergroups. Not all groups are open access -- some are closed and some may even have hidden memberships. If the board is open then you can request to join it by clicking the appropriate button. The user group moderator will need to approve your request; they may ask why you want to join the group. Please do not pester a group moderator if they turn your request down -- they will have their reasons.
How do I become a Usergroup Moderator?
Usergroups are initially created by the board administrator who also assigns a board moderator. If you are interested in creating a usergroup then your first point of contact should be the administrator, so try dropping them a private message.
