They can lock you out of your past emails, but they can't take your identity away if you use Google Apps for custom domains or MSN Live Domains. You'll still have access to your email address which would probably be "me@firstlastname.com" or something. Actually, if you make it a habit to schedule a weekly outlook download of your emails I don't think they can even lock you out of your email. I've taken steps to do the first part but I'm being lazy and not downloading all my mails onto my computer yet. [Effort vs. Payoff doesn't seem worth it yet]
