When you type your username and password in the login window, you will be ``logged in'' to Athena. While you are logged in you can read and send e-mail, write papers, play games, browse the web, and lots more. When you are done with your session, left-click the mouse on the ``EXIT'' button at the bottom of the screen to log out. Don't turn the machine off; once you have logged out, the workstation is ready for the next user, and the computer no longer has access to your data and personal records.
The large window on the bottom-right side of your screen is a ``terminal.'' This is a program that allows you to enter commands under Athena. You can start another terminal by clicking the athena% icon near the bottom-left of the screen. You can have as many terminals as you want.
