Epic Lameness

SF.net now supports OpenID. Hooray! I'd like to make a comment on a thread about the RTL8187se chip I've got in my new MSI Wind. So I go to sign in with OpenID and instead of signing me in it prompts me to create an account with a name, username and password for the account. Huh? I just want to post to their forum, I don't want to create an account (at least not explicitly, if they want to do it behind the scenes fine). Isn't the point of OpenID to not have to create accounts and particularly not have to create new usernames and passwords to access websites? I'm not impressed.
