FUDforum 2.3 supports a highly capable permissions system, which can be used to control what forum users can and cannot do. Using this system you can grant special access rights to certain users, block users from seeing and/or accessing certain forum etc.

This system also includes support for "group managers" who have the ability to manage users in the groups they control. This option allows the admininistrator to delegate responsibility to trustworthy forum members.

The Group Management is done via two control panels. The first control panel is the administrative group manager, which allows admininistrator(s) to add/remove groups as well as assign group managers and specify what permissions the group managers can assign and/or take away. This control panel also allows the administrator to make groups inherit permissions from other groups, which eliminates the need to specify new permission every time for similar groups.

The second control panel, the user group manager, which allows the group manager(s) and the admininistrator(s) to add and remove users from a group as well as set permissions for individual users. It can be a accessed via a link available to all Administrators and Group Managers on most forum pages.
