Having read one of your other posts I know what you are asking! If you know the person's screen name try searching for their posts. Maybe in their profile there's a PM or EMAIL. If you only know their real name, well there's not much you can do except post on different boards.
I have no idea how old you are, but try posting on the Teen board (if that was your age in 2001) or the Singles board. If they were cruise staff, try posting on the Crew board.
Good luck on finding your friend!
BTW, I'm an "old" Cruisemate, too
