My biggest problem is that MobileMe seems to provide the default mailing system. They keeping asking me for some password before sending mail. That's new. I have no idea how I can get the password they want.

I can send no emails. I can not order (e.g., a book) from a website. In the latter case they do not even advise you that it did not go through. I only figured it out when I received no confirmation (nor a book)

Can get no support, and I tried everything their online support offered with no luck.
