When I try to enter the General chat room, the message "You must be logged in to talk" is displayed.
Clicking "logged in" takes me to a page titled "Change OpenID" which lists OpenID providers. When I click one, I get the message "You are currently logged in. Do you want to log out and log in with this OpenID?". I then click the "Log in" button and am taken back to the chat room, which still displays "You must be logged in to talk".
This happened using Google Chrome 8.0.552.224 and Firefox 3.6.13.
