ATT Broadband Forfeits Mediaone Domain
Kancer was among the many readers to write with news (as carried by the Boston Globe) that "'beginning next month through March 15, current subscribers with (username)@mediaone.net addresses will be required to change them over to an address ending in attbi.com.' Also 'After March 15, any mail sent to a mediaone.net address will be rejected.' What a pain, looks like they are taking down pop mail and replacing it with web-based e-mail as well."
right now you have the choice of either. There is no preference at this time.
WebMail is for people who move around and want to check their account from non-attbi network connected computers.
Some people also prefer WebMail to using Outlook Express (the only supported mail client -- although there are instructions on the web for other clients)
