^^ Got to agree with the above post.
I can totally understand why that would be annoying to you guys, but for me personally, I've been on forums a LONG time. I tend to take a few days to read before I start posting. And when I *do* start posting, it's usually only on topics I'm interested in. So if I were restricted to one forum with newbies, would I post there? Probably not, to be honest. It's obviously your site and your decision, but it definitely wouldn't encourage me to be a part of it.
