Your electronic mail address provides the Internet with all the information necessary for messages to find you on the Net. It is quite likely that your best friend from high school who got married and moved to Sheboygan Wisconsin has some type of e-mail access, whether this is through the Internet, or CompuServe, or America On Line or whatever. Your friend might ask you for your e-mail address in order to send you electronic mail. In order for computers to be able to find one another on the network, it is important that they all have unique names. Computers are suffixed with Domain Names, names that attempt to descriptively tell who or what they are, these names are separated by periods.
Subjects are optional.
If you have new mail, you will be notified when you log on, or when it arrives. After you are done reading the mail message, type del to delete it. If you don't delete the message, it will be saved as old mail. Sometimes it is helpful to save important messages, but it is also important to keep the amount of old mail saved in your account as low as possible. Your old messages will be listed, entering the number of the message you want to read will bring it up.
