A The highest ranking users of the wiki, bureaucrats are primarily responsible for managing the staff themselves and have the ability to promote and demote other admin-level users. They also carry out regular duties like admins, such as code maintenance, content upkeep and user management.
Rollbacks are users who have worked as Moderators for an extended period of time and have shown a good track record in their work. As such, they have all the powers of a moderator, as well as the rollback ability, which can undo a large number of malicious edits on pages. They have seniority over moderators and are trusted to handle issues that moderators cannot.
Moderators are users who have the powers of Chat, Discussion and Content moderators. They have the ability to remove/restore threads and replies from any user, close/reopen threads, manage forum boards, move threads from one board to another, highlight/un-highlight threads, deleting blog comments, edit/delete article comments and moderate chat, as well as delete/move pages, deleting/moving files, re-upload files, protect/un-protect pages, and moderating chat. Moderators are the lowest ranking staff members of the community, and are entrusted with smaller-scale issues, such as commenting on applications, tracking user ranks, and helping users out with low-level problems.
