Hello everyone, I just joined your forum a moment ago. I hope this isn't a re-post, I did a quick search for OpenID and didn't find anything.
There appears to be some bugs with OpenID. When I tried to use OpenID to register, it went ok at first - redirecting me to the the openID site to confirm, but when I got back to select a username, the password validation failed even when OpenID was selected (since the password fields were blank). At that point I just typed in a password, and registered like normal.
When I tried to login with OpenID, it took me to the register page. This might be because of the problems during registration, though. Here are some logs from myopenid.com:
