Amongst a few other architectural changes on the site (disabling some unused modules, cleaning up code in our style files a bit, etc.), I have disabled the OpenID module on the website, meaning the one or two users who were using that for login can no longer do so.
To those users who are now having trouble logging in... email me with your account name, and I'll set up a password for you.
The reasons for doing this are twofold: 1. Only .5% of our users were using OpenID logins, and 2. The module wasn't working that well anyways.
