So I've given up on getting OpenID login working again; the straight-up Wordpress OpenID plugin has never worked for me (currently if I enable it it's in a state where it'll send you out to your OpenID provider, then when you complete that side it sends you straight back to my login page, un-logged-in) and the RPXNow plugin I used to use has turned into Janrain Engage and doesn't seem to work any more either. So I've turned them both off and re-enabled Wordpress user registrations, only adding a plugin that makes them protected by a recaptcha. Hopefully that'll stop the flood of spam registrations. Let me know (IRC or email) if you have any problems. Thanks!
