anon is a zephyr repeater, it works by taking the zephyrs you sent it, and resending them to a public class (-c anonymous). To see the zephyrs, you'd subscribe to the class as you would any other zephyr class. zctl sub anonymous \* \* to sunscribe for that session, or zctl add anonymous \* \* to add it to your zephyr subscription file.

to send a message to the class anonymously, you'd send it to anon, anon masquerades as a normal user. so just zwrite anon@zone.mit.edu

anon will preserve the instance you send with, so if you wanted your message to go to anonymous,foo,* you'd zwrite anon@zone.mit.edu -i foo

if for somereason you don't want anon to preserve the instance, you can use the opcode "noi". zwrite anon@zone.mit.edu -i foo -O noi

sometime there will be other opcode features. feel free to suggest some to us.
