I mentioned it before, that this is the only site of this type where there is not the equivalent of a front page listing every forum. It's made even worse by the way that some forums are tucked away in odd places. You need three or four clicks to get to a forum, where other sites would only need one.
I was stewing over it because I'm pretty sure there is a History forum, but I'm not going to waste any more time looking for it.
