Well it's good to know the name of someone
in charge. I kinda like to know who MOD #whatever is.
It actually makes me feel more comfortable on a board when I know who is watching it...unless I know that the person is irresponsible of course. But that's rarely the case in organized forums.
Revealing your identity isn't that bad.
I'm a super moderator (a mod with some administrative powers...it's a PHP hack) on another large forum and an administrator on another. Despite the size of the boards, I don't really get a lot of PMs at all and we don't have a "drop box" in either of them.
