A handful of errors stating that no username was filled in have been logged since yesterday. The Iron Bastard (heh) may be able to reveal more (cuz, basically, he KNOWS more), but I suspect it's related to the way member names, er, identities are currently displaying. But your profiles have all remained intact-- please don't worry about that. So if you don't mind waiting, you may want to put off making a big change to your profile such as a new password, username, or email address til the, ahem, identity situation has been resolved. It's just a suggestion for anyone that may be having this problem, and of course the other IB might come along and say otherwise, though not if he knows what's good for him.

If you're anxious to show off your new avatar now, you can IM the URL of the image (to the name
admin, though I understand how tempting it is to address it to Iron Bitch, hee hee) and I can try to change it for you, hopefully without getting the same error. The current forum setup requires that avatars be no larger than 82 x 86.
