It can be very annoying to have to close Barnowl when you turn off your computer. During the time your computer is off, you're missing many (possibly important) zephyrs. It can also be frustrating if you leave your computer on with Zephyr up, but go to a different computer and want to check your zephyrs - how do you do this? These problems can be solved with the magic of screen.

=== Screen ===
You should find a computer or server on which to run your screen session(s) that is up all the time, for example, linerva.mit.edu. Screen allows you to run programs inside of it on one computer, and to access those same programs from other computers via ssh.
Note: It is always a good idea to check the status of your sessions by means of "screen -list".
+The -x option is preferable, since it means you don't need to reattach your screen elsewhere if it was previously attached.

== Traditional Zephyr (archaic) ==
When you log into Athena, you may occasionally see a white box pop up with text on it. This is Zephyr in it's traditional form.
