I don't know all of WHiZZi's criteria, but one is whether we need a mod or not. Dave and I were invited at the same time, WHiZZi was too busy, and InSoft (did anyone ever see him online?) was never here, and Jon was busy too.
Anth came in as a mod because we had gotten bigger and Dave and I weren't always online. The reason Anth was picked is because he was already doing a lot of stuff to help us out, compiling lists/links etc and he was here a lot. He seemed responsible and I suggested him to WHiZZi and Dave agreed. He's done a great job, but don't let that influence you at voting time for Best Mod.
Dave became Admin because we needed greater than mod power on the board more often. There are some things that Mods can't do (IP bans, creating new forums, changing member names) and WHiZZi and Jon just aren't online as often as we sometimes need.
Dingo and CatraDthem are "specialty" mods. Dingo maintains the spoiler board when it's active, and CD maintains the Tourography and Rock Hall stuff.
Ryan's just in a class by himself.
Oh yeah, that Al guy can wield Admin power if he wants to.
At the moment, I don't think we need anyone else, but of course that's WHiZZi's decision to make.
