crypto community

Just had a fun idea.

It's like a little web community online, but every message you post comes with a "cryptcode" so that people know it was you that posted it.

Also maybe other fun things to do with cryptography. Any ideas? Does such a thing already exist?

Post user IDs? Of course. Even Shiichan used to have those IDs (check old posts). They're usually an option in the config file for most text board software.
