I think I fixed the login problems which have kept the forum mostly dormant for ... at least a couple of years. The key was some combination of updating the forum software and disabling the integration with cmubuggy.org's own login system. For now it should let us have conversations. New users should be able to register.
In the mean time, I seem to have lost the custom theming, but I'm at work and that is non-critical in the grand scheme, so I'm going to punt on that for a bit. Enjoy the blue theme!
