Windows Live .NET Passport Sign Up
A Windows Live ID can be used for multiple purposes and on all those sites that support Live ID.
You can use your any email address by any email provider on MSN Messenger, Windows Live Messenger, or anywhere it asks you to use your .NET Passport.
Example: I’m using my Gmail’s email account on MSN Messenger. Try it yourself, add me and see firstname.lastname@example.org.
