There are six kinds of users with additional powers on Legacy Wiki-moderators, discussion moderators, administrators and bureaucrats. * Discussion moderators have the power to remove posts on the discussions board. * Moderators have the power to roll back edits with just one click. * Administrators have the power to - in addition to the powers of a moderator - delete pages, protect pages and ban users from the wiki. * Bureaucrats differ from regular administrators in that bureaucrats can give and revoke other people's administrative powers.
