Give me a moment to figure out where to start. My guess is that it won't be a busy one (who ami I kidding; none of them are that busy.)
And usually the applications are the simplest. There's no way of knowing an applicant's admitted age as you would in Yahoo (funny story, I moderated a Yahoo group with a couple of fetish models in it who had their age listed as 99)
The main thing will be moderating posts. If you get suspicious posts (ones that look like they're spam or contain viruses, block them and ban the poster).
