We have added support for OpenID to this site so that our commenters don’t have to manage yet another password. If you are creating a new account, you can create it with an OpenID from the start on the registration page. If you have an existing account and would like to link it to an OpenID, just log in with your existing account credentials and click on the “Your OpenIDs” link on the left of the user management page and do the linking there.
Awesome
