We are now running the latest and greatest version of vBulletin, and all is well, aside from a glitch in the avatar system. For the moment, I've put all of the avatars we were using into the public avatar database, so you'll have to restore your own avatar as follows:
Go to "User Control" at the top left of the forums. Then, under Settings and Option, go to Edit Avatar and choose your avatar from there.
Hopefully, I'll get the avatar system repaired soon, so I can remove them from public view and maintain everyone's unique avatars.
Aside from that, let me know what you think! I'll just be hiding in an underground bunker...
