The first email systems were used to send messages from one computer terminal to another on the same computer network. Messages were addressed to individuals on the network or to computer workstations on the network, such as terminal 22. For decades, computer users had to be at a certain computer to check their email accounts. Today, you can check your email from your normal computer or remotely access your SBCglobal (AT&T Yahoo!) email from any other computer connected to the Internet. All you need is your member identification and password.
