Well, the best way, would be to make another subforum, because, obviously, this entire Android forum is going to be HUGE! Soon it will be full of differents ROMs, FAQs, Random questions, and people's own threads about their experiences.
So I agree, if we don't do anything soon, this forum is going to end up in a huge mess.
Either some admins are appointed, to cleanup and simply REMOVE all the spam threads, or else there's a need for even more sub forums, one to ROM releases, one for questions and answers, and one for general discussion etc etc.
THats just my opinion.
