Just something I've noticed: The url
www.rmrk.net will cause you to go to the forum, but if you're logged in this url will make it seem like you're logged out. Clicking the "forum" button proves otherwise, but just the same this error persists. Also, logging in from the sidebar on this page doesn't work 90% of the time. It will ask you to log in a second time almost invariably. I'm not sure why this happens, but I thought I'd bring it to your attention Roph.
Second, I think the chat link would be better suited as a large button, somewhere between home and perhaps search. I think that would promote IRC activity and it really makes more sense in my opinion.
