We don't necessarily need people to deal with trolls.
For the most part we just let them burn out, most people on these forums know not to feed the flames of the trolls, and it ebs and dies with the seasons. The forums get dead, the forums come alive, people get restless, the forums get dead, the forums come alive... rinse and repeat.
Mods aren't here to wield ultimate power on your conversation choices. We just make sure rules are followed. Stray from the path, face the wrath... but... even then, we tend to just quietly move things away, reset the chat area (by cleaning up the every-once-and-awhile mass of OTT's) and watch for signs of problems.
We (and by we I mean me, I don't speak for all the Mods, cause that'd be weird...) don't like to play police-man on the forums. I personally like chatting, answering con questions, asking con questions and finding out about cool meet-ups/news and fan stuff going on. Thats what I use these forums for.
Oh dear me, I can't seem to stop typing... it looks like my wall-o-textitis is coming back...
We like applications for Forum Mods... just make sure you want to be a Jedi for the right reasons. There is not a lick of glory in it.
