Write

Yet another feature that I never needed before:

Send message to another user:

  write <user> [terminal]

The other user sees the message, but his terminal is still looking for commands. The cure for this is to use write (by itself, it assumes you are talking to the other user) to initiate a reply.

After that, it is just like any other chat, until each user presses ctrl-d.
