-> Literally, "Pseudo-Random Neuron Firings".
-
-There are many other acronyms that are used; if you don't know what it means, try using the `whats foo` command at an Athena terminal. If you don't have the command, run `add sipb` first.
-
-### Startup
-
-There might be some options that you want to be consistent from session to session; you don't want to have to set the same variables each time. You can fix this by adding the commands to your "startup" file, for example, `.owl/startup`. This can be done from within Barnowl, by using the `startup` command:
-
- :startup set foo bar
-
-Where `foo` is the variable you want to set, and `bar` is the value. You do not necessarily have to use the `set` command, either, any command you can type in Barnowl can be added to the startup file.
-
-### Logging
-
-It is handy to be able to log your conversations so you can refer back to them later. To log classes, for example:
-
- :set classlogging on
-
-And to log personals:
-
- :set logging on
-
-This will log to the "zlog" directory in your locker. You probably don't want people to see what classes you're on or what people you talk to, so you can run the Athena command
-
- mkdir -p ~/zlog
- fs sa ~/zlog system:anyuser none
-
-to make this directory completely hidden.
-
-### Colors
-
-By default, there are seven colors you may use in the terminal: red, green, yellow, blue, magenta, cyan, and white. In order to use color in Zephyr, you can use the following notation: `@(@color(red)This is some red text))`
-
-Colors may vary from machine to machine, as different terminal profiles may have different shades of the seven colors.
-
-### Filters
-
-Some people like to customize their Barnowl by color-coding classes. This makes it easier to tell different classes apart (and minimize mixing). Barnowl has some already existing filters, for example, `personal` (for incoming personals), `out` (for outgoing personals), and `ping` (for pings). To assign a color to a filter, add the following to your startup file:
-
- filter personal -c green
-
-What if you want to color-code your class, or a friends class? You can create and color filters with:
-
- filter johndoe class johndoe
- filter johndoe -c blue
-
-You can update your settings and filters without restarting your Barnowl session by:
-
- :source ~/path/to/config/file
-
-You can see all the filters by using `:show filters`, and narrow to a particular filter with, e.g., `:view personal`. You can use `:view all` or the keyboard shortcut `V` to see all messages again.

-## Running Barnowl in Screen
-
-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 be aggravating to be using zephyr via an unreliable network connection. 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.
