Altcoins with plaintext transaction messaging I'm looking to compile a list of altcoins with plaintext transaction messaging embedded into the blockchain. If anyone knows of a coin that fits the bill then please share.

  The NXT Messaging system allows you to send and receive data on the
  NXT Blockchain, thus allowing any Nxt account holder to communicate
  directly with all other account holders.
  
  Messages can be attached to any Nxt transaction, making bookkeeping
  easy, as you can tag all your transactions with a description. Project
  developers can use the Messaging system to embed machine-readable data
  within an Nxt transaction. This allows automated functions by reading
  the data sent to you on the blockchain.
  
  Messaging is securely encrypted by default, but text or data can also
  be sent unencrypted.
