3.3.2: Group Permissions
This panel will allow you to control a group's access to private forums. It will also let you specify groups as moderators of a forum. If a group is moderator of a forum, then each of the group's members is considered a moderator of that forum.
To edit a group's permissions, select the group name from the dropdown box, and click Look Up Group. To grant moderator access to a group, look in the desired forum's row. In the last dropdown box in the list, choose Is Moderator.
18.104.22.168: Simple Group Permissions
To grant a group access to a private forum using Simple Permissions, Choose Allowed Access in the Simple Permissions for that forum. Choosing Allowed Access is the same as setting all Advanced Group Permissions to ON.
22.214.171.124: Advanced Group Permissions
Advanced Permissions will allow you to grant specific behaviors to a group. In the Advanced Permissions panel, there will be a dropdown box for each Permission type that is set to PRIVATE in the Forum Permissions panel (for more information, see 3.1.2 Forum Permissions). To grant the group a specific PRIVATE permission in a forum, simply set the appropriate dropdown box to ON. To grant all PRIVATE permissions of a forum to a group, use Allowed Access in simple mode.
