I don't really blame the gay teens for having an age limit. Any teen forum must have a VAST troll/creep pool. Although i am probably older than most of their Moms, i would consider it but I am still spread a bit thin IRL, and Recruitment is about to start as well as a game I am modding (in our forum, that is monitoring it, not the same as GMing as you mean, we say "Host" for that). Plus another I have to help the host set up for as it involves making sockpuppet accounts for some 30 odd roles.
So post again in a week if you still need people.
