"Moderators" moderate specific sections. They can delete posts there, edit them, move topics, split topics, lock topics, and sticky topics. "Global moderators" are the same as moderators, but they moderate all sections. All staff can also whitelist newbies and ban newbies. Administrators can do anything.

Any user can report a post. The report is send to the admins, global moderators, and any applicable section moderators. The recipients choose to act on the report or not.
