Hello! Welcome to the Administration page! Chances are, you need something, and you are looking for one of us! You are in the right place!
A bureaucrat is a user with the ability to promote or demote other users. Bureaucrats also have admin privileges.
Administrators, or admins, are users who have special privileges to the wiki, mostly security and maintenance, such as blocking disruptive users, rollbacking vandalism, and deleting/restoring pages. Admins also have chatmod and rollback privileges.
A rollback is a user who has the ability to "rollback," or revert vandalism very quickly.
Chat moderators, or chatmods, have the ability to kick and ban people from chat.
