That's probably because there is so little to describe.

  Agree on keys with your gang.  (Shared secrets or public keys not otherwise
  recognisable as yours.)

  All of you regularly download all of alt.anonymous.messages that you have
  not yet seen.  Then (offline to avoid revealing timing data) you decrypt
  all you can and read it (throwing away the rest).

  To post anonymously to alt.anonymous.messages use mixmaster and a mail-to-news gateway.
