Recently it came to my attention that the first (and, until recently, ONLY) successful e-commerce ventures were porn sites. Now, this just now got me thinking - why not make the galleries and downloads at Renderotica pay/subscription based? The forums there can (and should) remain free, but by putting a fee on the galleries and downloads, you could do a sort of check on ages (in theory you have to be 18+ - or an emancipated minor - to get a credit card, so this would essentially make the 18+ concept there easier to enforce), make some revenue, and otherwise pretty much keep things as they are. It may be totally insane, but it's a thought... :-)
