When I first start using Internet message boards, the regulars on the board that I joined suggested to newbies that it was a good idea to have a handle rather than using your own name. I needed a name in a hurry so picked up a book from the shelf above me, opened it and picked a name off the page. The '936' is just a random set of numbers that's quick to type whenever there is more than one Selenay registered on a system. Not particularly clever, but it's stuck for over five years now :-)
