* [[Using Zephyr|doc/zephyr]] <br />
A guide on using Zephyr today with BarnOwl (and GNU Screen). Aimed at newcomers to Zephyr, and a pretty good reference. See also [the BarnOwl wiki](http://barnowl.mit.edu/).
+* [[Using `zcrypt`|doc/zcrypt]] <br />
+A guide to using `zcrypt`ed (encrypted) zephyr classes. Zephyr at MIT (mostly) doesn't support limiting who can sub to a zephyr class, so if you want to have reasonably private conversations, encrypting them is a good idea.
