But unless you re-do how the Moderators work, you will never get 24/7 coverage. For example, the Purple/Princess boards - no one would be as "strict" as they are, so there would be no one else that could help watch those board.

Unless you make some "global" moderators who have access to edit out bad words & personal attacks on all public boards - possible with the rule that the "global" moderators mostly just edits and hides and lets the "regular" moderators choose if they want to ban or keep hidden the user. BUT AND I STRESS THIS MUCH - If you do have global moderators for the public boards, you HAVE to have someone who is fair to all - not like some current board moderators.
