One suggestion I had, even though seem capt has a new plan anyway, was to give the schill winners a small part of the prize money and redraw two winners for remainder based on a one month forum start date or proof of sales on main site, smth as such.
That way schills get a free kick for $500 or smth for effort but the prizes reward actual members and not spammers.
Either way, I'm just grateful they ran it, when they didn't have to at all.
Cheers
