Re: 404 message
It's odd that I haven't had any trouble hitting the main page. I only have been getting the error when I try to dive into a game or forum. It makes me think that it is an authentication issue, because I think that the main page can be painted (even with highlighting games' post count in red, I bet, since that's done on the browser from cookies) without actually checking authentication. Hmmm. Except that it does need to access your list of games you participate in; I can't believe that's kept in cookies.
Well, it was a thought. It is definitely consistent, though. I've even tried a shift-refresh on the main page, and it works fine, but then trying to open a forum or a game gives me the 404.
