I think it is a good Idea to have more moderators. With LordDouche Down Under and slavelucy in Europe, the GaryWilcox / redEva team in the east coast and TG and FF out west, the forums are covered practically full time.
Also if one of the moderators is out of line because of a personal implication in a forum discussion, there are more chances another moderator can step in and help everyone keep their cool.
