I have to sleep sometime. It wouldn't hurt to have a couple moderators in different time zones...

Off hand I can't think of many people who may want to volunteer who have been around awhile, are generally helpful and have not gotten involved in any flame wars (even if they were 'right'). Arguing is fine, but if I make someone a moderator it would convey some official endorsement and their posts would reflect on Larian, so they could need to remain mostly professional (I'm not claiming to be perfect in that regard myself).
