This simple program runs on most mail servers on campus and can be accessed by typing pine from a Telnet session on your mail server. What is even better about Pine is that almost every function you could possibly want to use is documented on the screen in plain English.
No setup is needed. Simply open a Telnet connection to your mail server and type pine. The program is already configured to handle your mail account based on your login to the server.

Pine commands are shown at the bottom of each screen. There are different commands depending on where in the email program you are. For some of the commands, you may see them noted with a caret mark: ^J, for example. This is a shorthand for "Control-J". If a caret mark does not appear next to a command in the bottom part of your screen, you don't need to use the control key, just type the letter itself. These commands are NOT case-sensitive.
Press C to go to composition mode. You will be given a screen with addressing info at the top and a blank space below a line for the message. You can type in the addressing info and subject, using the tab or arrow key to move back and forth between the fields. When you are ready to compose the message, tab to the Subject field and then hit Enter. Once you are done composing your message, you can send it (^X), save it and postpone the sending till later (^O) or cancel it and delete the message (^C).
