The moderator on the Google Problems group encrypts his messages so
they can't be searched, but when you open them up the decrypt by
themselves. So I've been running searches for other people who use the
same kind of encryption and have found a few of 'em, but I can't even
read their messages because once they are decrypted they are in Hindi.
But here is a link to one author who can do this too.

Also if you read the moderators messages on the google problems group,
you can get chunks of the code that are both encrypted and decrypted,
so it should be easy to find correspondences (at least with his
algorithm).
