BTW...this whole JD Gamertag sharing idea was a good one, but more people should post theirs here.
Well, you're right, more people should, but you gotta wonder:
How many people post here on a regular (or even semi-regular) basis, and of those people, how many people have an XBox, and of
those people, how many have a Live account, and of
those people, how many people, for whatever reason, are willing to share their GamerTag?
Ain't too many people other than the handful who already have, I'll bet. . .
