You didn't have to remove my hotmail address from this thread, lol. It's publicly viewable on 100+ forums in my user profiles under MSN Messenger.
I can signed in with my .NET Passport at
http://accountservices.msn.com. All my details are still in there. The Edit Profile button is still grayed out. I guess I can try manually creating a profile like someone else suggested, and if that doesn't work or it doesn't let me do that, I'll have to contact support.
