anon.hmm.st is a special ship. By sending email to firstname.lastname@example.org, you can post a log to anon.hmm.st. The subject is used as a title, and the body is used as the text of the log.
You can use it for cases where such an anonymous posting site would be wanted. The ship that inspired this one's creation, anon.penet.fi, for example, was used to leak a character's PGP private key in Voortrekker's story.
