 Note Board system, (c) 1995-96 Erwin S. Andreasen, erwin@andreasen.org
 =====================================================================
 
 Basically, the notes are split up into several boards. The boards do not
 exist physically, they can be read anywhere and in any position.
 
 Each of the note boards has its own file. Each of the boards can have its own
 "rights": who can read/write.
 
 Each character has an extra field added, namele the timestamp of the last note
 read by him/her on a certain board.
 
 The note entering system is changed too, making it more interactive. When
 entering a note, a character is put AFK and into a special CON_ state.
 Everything typed goes into the note.
 
 For the immortals it is possible to purge notes based on age. An Archive
 options is available which moves the notes older than X days into a special
 board. The file of this board should then be moved into some other directory
 during e.g. the startup script and perhaps renamed depending on date.
 
 Note that write_level MUST be >= read_level or else there will be strange
 output in certain functions.
 
 Board DEFAULT_BOARD must be at least readable by *everyone*.
