Alot of new members tend to get intimidated when they see nothing but moderators all over the board... One thing that I do is disable the moderator column on the main forum display... if someone wants to know who the mod is for that forum, well then I guess they are just going to have to go to that forum....
It also helps to keep the mods a little 'humbled'... they are actually going to have to do some posting in order for their spiffy title to be seen...
