@dynoro: Hmm, these are both 404ing for me. Where are you seeing the links to these pages?
The URL is displayed inside of the Giant Bomb XBMC plugin when you try to link a subscriber account to it. There was another thread about this bug in another board recently (I think General Discussion) where I noted that this page was working fine for me up until a few weeks ago.
Edit: I just realized it's 404ing because the board is adding a trailing slash to the URL. If you remove that and press enter the page will load correctly. This seems to be a bug with the way the forum or site parses some links, rather than the actual XBMC code page.
