I agree with Dorian: yes to forum moderators.

There seems to be some misunderstanding about what moderators do. They do not:
[*]alter posts[*]allow flame wars to spread[*]interject his or her own opinions[*]allow personal bias of community members to get in the way of his or her moderation duties

A good moderator is expected to remain impartial and should pretty much sit back unless or until a thread turns ugly or otherwise runs contrary to the stated guidelines (which need to be made clear in advance) of the forum.

Check out the Plane Business boards for an example of a successfully moderated board.
