Tag Names for machines and Nick names

Ok I talked to one of my buddy's and he thought that a good topic to talk about was gamer tags, you know the names you leave on the machines when you get high scores, mine is MB which is basically my inititals. Think about it and you really introduce yourself to people you've never even met going to a machine that has a high score with the letters DOC or ALW and you wonder who these people are, then also how much you want to get the score for whatever song or course that is on the machine that is your favorite of course :-). I've met a lot of people over the course of dance games with different tags, some such as "Guru" "PNCH" "JJXX" "JLG""M4XX" and so on, although these are people I know in real life now, I really don't really refer to them by their names, everyone calls eachother by their game tags which is funny in my opinion but its pretty cool down the line and in a way shows some sort of respect for the other players.
