forget, my name's unoriginal.
Anyways, I think that if someone is already named "MasterCheif" and then someone else trys to name themselfs "Mastercheif" and it doesn't work because that name is tooken and they just add numbers onto the end of it, even if it's a birthday, lucky number, anything, it's still just a way to "Take" that name even though someone else already has something very similer to that name, I mean you're never going to remember someones name if it's "blahblah392928392" but you will if it's "BlahBlah". So, in conclusion I think that random numbers at the end of any name is useless and idiotic.
