Yogscast Wiki:Forum Moderator

Moderators are users who have additional options available to manage thread conversations in the Forum and Message Wall features. They can remove and restore threads and replies from any user. They can also close and reopen threads. In the Forum feature specifically, moderators also have the ability to manage Forum boards, move threads from one board to another, and highlight and un-highlight threads.

Having this status causes "MODERATOR" to appear next to the username on the user's userpage.
