Hi, no1nos, and welcome!
I'll admit that this is a pretty daunting thread to go through, but I don't mind if a question has been asked before.
In fact, I think that's a sentiment that's fairly common amongst the membership here. We won't think bad things about you if you start a thread about something that we've already discussed. Just make sure it's not on, say, the first page or two, and you'll be fine.
As a rule, the way a new subject-based forum gets created here is if the subject starts to overwhelm another forum here. That's why there's a Global Warming subforum and not, say, a Sports forum. If Astronomy or CT topics start crowding out other science/skepticism threads, we'll make a new forum for them. Until then, go ahead and start threads on topics like those in Skepticism/ Science.
