This is a addon that goes into the note.c file
it allows for when a new message is posted that it notifys whoever it is too:

In note.c just after the message sent notice in void parse_note put this:

 sprintf(buf,"A knight rushes up to you, \"New %s for you, sir!\"
, you slay him and take the message from his corpse.\n\r",note_type_lookup
(type));
          send_to_char(buf,d->character);  

Voila
