 Here are some of the primary clients used at MIT. There's also a listing of [other Zephyr clients](http://zephyr.1ts.org/wiki/ZephyrClients), but their use is generally not recommended.

-[Barnowl](http://barnowl.mit.edu/) is a command-line Zephyr client that supports advanced filtering and customisation. It is probably the most commonly used client, but requires some effort to get started. To use Barnowl effectively, you should connect to an [Athena dialup](http://web.mit.edu/dialup/www/ssh.html) and run Barnowl along with a program to renew your Kerberos tickets. The Athena command `athrun sipb owl-screen` will set this up for you.

Zulip was originally a proprietary product developed by a company composed largely of MIT alums and SIPB members. It was acquired by [Dropbox](https://www.dropbox.com/about) in 2014, and [released as open-source software](https://blogs.dropbox.com/tech/2015/09/open-sourcing-zulip-a-dropbox-hack-week-project/) a year later. The Zulip for Zephyr service is offered by [Tim Abbott](http://web.mit.edu/tabbott/www/) (MIT '06, SIPB member)'s Kandra Labs.
 
 Zulip, like Roost, is easy to set up because it uses Webathena for authentication.

+You can send zephyrs to individuals (as opposed to classes) with:

+
+It is possible to `zwrite` to multiple individuals at once, by listing the

+The `-C` option automatically puts the line `CC: USERONE USERTWO USERTHREE`

+
+### Aside: zephyr triplets
+
+All messages are actually sent to a "zephyr triplet" &mdash; a class, instance, and recipient. Subscriptions are also made to zephyr triplets. The recipient can be either "*" &mdash; to indicate a broadcast message &mdash; or a specific individual.
+
+When sending, the default class is "message", instance is "personal", and recipient is "*". `zwrite` supports sending to arbitrary triples with `:zwrite -c CLASS -i INSTANCE USERNAME` &mdash; the two examples above use the defaults for the parts that aren't specified.

+For subscriptions, the class must be specified. You can specify all instances on a class with "\*", or specify just one instance. You can only sub to recipient "\*" or your own personals (indicated by "%me%").)

 If you spend enough time on Zephyr, you'll begin noticing some strange
 phrases and words being thrown around.  Some of these include:
 
 <strong>i,i foo</strong>:

-> just like saying:".  Sometimes people simply use quotes: `"foo"`.

+> for similar purposes.
 
 <strong>mix</strong>:
 > If somebody accidentally sends a Zephyr to the wrong class or
 > person, they will send another Zephyr to that wrong/class person
 > simply saying "mix".  This basically just means, "oops, sorry, I
 > didn't mean to send that Zephyr here".  You might also see "-i mix",
