Quote - I'd imaging that's cuz the forum is on the same server as the Marketplace.....

Err ... no the forums are now being served from something that isn't the marketplace server.

If you go direct to the forums (on excalibur.renderosity.com) then you have to login as this server isn't processing the auto-login cookies the the main server (www.renderosity.com) hands out, whereas the marketplace server (market.renderosity.com) does process the cookies and then hands out some more which the new forum server does process.
