Print some tips for new users
mw can be confusing if you've never used it before:
CHANGE: Created user newuser: John Doe firstname.lastname@example.org
CHANGE: Auto-registered newuser
SYSTEM: newuser has just entered the board.
newuser has just joined talker room 0
SYSTEM: newuser's connection has just dropped.
so it should print some brief getting started tips for new users. How to quit, how to start chatting and how to find more help should be the main points.
