mr brakes..... I know the catch 22 situation..... I know the pain of building a site and waiting... waiting... waiting....
But is such a bot really the answer? get out there and meet people in the real world, lead them to your site, sponsor some events with cheep gifts in exchsange for exposure, do the footwork - thats what pays off. A sites growth is a reflection of the work you put into making it grow, of how many hands you shake and potentioal members you talk to.
Its a long, tough road, but if you want a decent membership its probably a road you are going to have to tread...
