I don't really care about what order you put the forums but I was just struck with a thought about them. My apologies if I'm repeating someone else's ideas.

It seems to me that having the For Sale and Wanted forums at the top of the page (and for some of us the only ones visible without scrolling) it may send the wrong message to new viewers. This site isn't primarily a Sale board but it might look that way to them. Just a thought.
