"message system" between users

could be nice to have a "message system", that users can send other users a message.

it can be made of 2 none-visual components:

  1. the "sender" component
  2. the "reciver" comp.
    maybe also same components for DB.

possible properites can be :

  1. UserID
  2. Title
  3. Description

the reciver will get a "jumping" message the "Async-way".
