The bulk of the glitchiness seems to have been taken care of, at least with basic functions, and so tomorrow (Monday) I'll be ready to try to get usernames and logins imported. I'll update and let everyone know what's happening with getting new posts up and going at least. And then I can work on getting old entries and comments imported after that. But the more immediate goal is to allow everyone to at least resume with new content while I figure out how to restore all of the old.
I will be so damned glad when this is all fixed.
