Lose e-mail address if leaving AT&T DSL?
Even if this isn't strictly travel technology, I hope I can get away with asking it here or be redirected. I'm considering moving to my cable company's Internet, away from AT&T DSL. Would I lose the sbcglobal.net address (Yahoo mail setup) that I have through AT&T? I only use it for commercial signups, and I wouldn't miss most of the mail, but in some cases it's my only notice of bills, and I'm not sure if I'll find them all to set up an address change.
