I was a regular on a forum a long time ago....it started innocently enough, and then I began to realize I couldn't be myself when responding, because people see "moderator" and instantly think you are in a position of more knowledge, and more power, therefore taking what you say to heart. Then it sometimes backfires, lol.
I know mods move threads, and keep spammers at bay, so why not just have someone do that part? Maybe using a "forum maintenance" title, or something along those lines? I just don't see the need for mods...not as far as argueing goes. I think although some of us may read a post wrong, or get 'bent' on occassion, we tend to step back and regroup, or inquire as to what was meant. From what I've seen, we mod ourselves pretty well.
So IMO...maybe just a 'maintenance' person? That way, they can still be themselves, and not have so much pressure.
