I used to be a mod here, but resigned because I was naughtier than the kids I was moderating; but I also Mod another site. Personally I wouldn't want to mod here again because I prefer being one of the kids, but if anyone wants to mod I suggest they send an e-mail FAO Mike Boxhall at admin (the e-mail is at the bottom of each page).
Just write a bit about yourself and explain why you want to mod the site. If Mike agrees its not a problem adding another Mod, he'll just have to give the tech guys some details, and in a week or so you'll have all the extra 'mod buttons' and access to another part of this forum where the mods talk about us behind our backs.
But I don't think Mike comes here much these days, so he might either ignore you or tell you to f*** off.
Maybe Dave could stick a post up on the moderator section of this forum asking for more mods? Personally I think we could do with another; just for when Dave is swanning off on one of his foriegn holidays!
