The colors are alright, I guess, but we don't really need another Talk about anything you want forum. That's what chatrooms are for. If people just want to talk about anything, they would much prefer do it live, rather than posting sentence-by-sentence. I've seen a very small amount of these types of forums actually work. I suggest making a site with some kind of other purpose, then, if you get lots of hits and good comments from your visitors, perhaps open up a forum about your site.
