Some here apply even a five-year criteria.Ahhh, Mr. "Since Jun 11, 1998", I've got your number.
But I'm thinking it should be closer to three years (closer to my May 10, 2000 freeperdate ;--)
I'll defer to your judgment on that one - actually, we are both stretching the point a great deal for the sake of humor, and ignoring the fact that it should really just be a content-based judgment.
