I can't login to the forums on my main account, nor another account that already has a forums account set up. It goes to the auth page, redirects back to the forums and just hangs. I see some people are able to log in, but the number of posts seem fairly low for a new test patch just being released. Creating a new forum account on one of my other accounts DID work... the redirect worked as expected once agreeing to the T&C. But that's a different process than simply logging in.
