Yahoo! Mail is changing the design of the web interface, and Neal is having problems adjusting to it. He can choose the "basic" layout, but there will be no way to go back to the layout he's used to. Leo says that this new "purple" version of Yahoo! Mail is pretty good, however.
Neal could get a Microsoft Live Mail account at get.live.com, and then get Yahoo PoP3 access to download his mail to the Live Mail desktop client. He can also create a Gmail account and then have GMail retrieve his Yahoo mail, and forward new mail to his Gmail account. Then he could use a desktop client such as Thunderbird. The point of this is to use a desktop client where the interface won't change on him, and has a more classic user interface.
