As for the info not saving, do you use Firefox by chance? I've seen a lot of reports over there of the new software not working too well with Firefox. I don't use Firefox, but haven't had any problems with Opera, Chrome, or IE 6.
I've now tried with Chrome and that doesn't work either. I can save my privacy preferences but my actual profile stubbornly refuses to save. There is no error message or anything, everything seems normal as I enter the data it wants, then it asks for my username and password to save the changes, but the red X that indicates that I haven't entered the profile information does not disappear, and if I click on it again everything is blank.
