+Many SIPB members and prospectives [use zephyr](http://sipb-www.scripts.mit.edu/doc/wiki/UsingZephyr) to communicate about
+projects, discuss what's new (or old) in the computing world, and
+generally keep in touch. Here's a list of some zephyr classes you
+might be interested in subscribing to.
-* '''<sipb,*,*>''' - The general class for SIPB members and prospectives. General discussion.
+*Note*: If you're new to zephyr or to any of these classes, you're
+encouraged to just listen to the class at first and get a feel for the
+class's typical modes of behavior. If you jump right in, you might
+risk accidentally offending someone.
+* **<sipb,\*,\*>** - The general class for SIPB members and prospectives. General discussion. It's considered polite to always use an instance when sending to **-c sipb**. *High traffic.*
+
+* **<sipb-door,\*,\*>** - Receives a zephyr whenever SIPB's office door opens or closes. Great way to keep track of whether the [[office]] is open or not.
+
+* **<sipb-auto,\*,\*>** - *High traffic.* Receives a variety of automatically generated zephyrs, including...
+ * **<sipb-auto,sipbmp3,\*>** - Activity on [sipbmp3](http://http://sipb.mit.edu/sipbmp3/). *Usually high traffic.*
+ * **<sipb-auto,sipb-door,\*>** - See **<sipb-door,\*,\*>** above.
+ * **<sipb-auto,sipb-www,\*>** - Commit logs when changes are pushed to this website.
+ * **<sipb-auto,backups,\*>** -
+ * **<sipb-auto,nagios.stuff.HTTP,\*>** -
+
+## Classes for SIPB Projects
+
+In general, you should only sub to these classes *if and only if*
+you're interested in helping with a specific project.
+
+* **<scripts,\*,\*>** - If you're interested in getting involved
+with [Scripts](http://scripts.mit.edu/), subscribe here to see what
+the Scripts team does behind the scenes. *High traffic.*
+
+## Other Useful Classes
+
+These are not SIPB-related classes, although many people affiliated
+with SIPB and/or IS&T listen to them. In general, you should not send zephyrs to
+any of these classes.
+
+* **<consult,\*,\*>**
+
+* **<filsrv,\*,\*>**
