I suppose I set myself up for that one.
Anyway, I believe that the first thing done should be to clean out the inactives of the admins on the Steam group, and put a group of active, trustable players into admin positions.
Next, give the new admins rights to create events, tell them how to make events if needed, explain to them that events should not be spammed and that events should not be biased towards any clan (should we choose to do so) unless it's required, such as a skill server event and there be only one skill server.
What could go wrong! (Now that I've said that...)
