Extension:UserGroups

The UserGroups extension adds a special page called Special:UserGroups that allows the user accessing it the ability create, delete, modify and configure user groups in terms of the user rights registrations or associations with it. It could be thought of as a revival of the now defunct Extension:GroupPermissionsManager. This is different from Special:UserRights, which only determines how to allocate user rights to certain users based upon membership of certain user groups.

User rights

 * modifygroups: Determines control of access to the Special:UserGroups special page interface, or in essence who is allowed to modify and configure user groups and their associated permissions. By default, this access is restricted to bureaucrats.
