My suggestion:
More bots to be public.
It seems all decent bots are at least UGS and sometimes UGB. If some decent bots, not all, but some bots are public, we could advertise the shit out of them and get members.
After making bots public, it'd be easier and more affective to advertise.
Just something I thought I'd post to see what people would say.
