ending in @sbcglobal.net? I have an elderly relative who has a current sbcglobal.net acct but is switching from AT&T to another provider.I assume when he switches to the new provider, the sbcglobal.net email address he has will disappear, yes? He wants to continue to have a free yahoo email account after he switches providers and to export his current address book into a new yahoo email account.How can he do this?
