Anyone can revert vandalism and bad-faith edits, but it takes a couple of clicks in the page history to get it done. Users with the "rollback" permission are able to undo bad edits with one click, by using the rollback link on diff pages, user contributions list, or the list of recent changes. It is important to note that admins already have rollback rights by default. Users with rollback rights are just users who are not necessarily an admin.
The following users are Glee RP Wiki current rollback users.
