[[!meta title="SIPB Zephyr Classes"]]
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.
*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/)
* **<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.
