I made another list. Why? Your guess is as good as mine. It started out as just being major New X-Men, Young Avengers and Runaways. I don't recall why, but harmless enough; keep track of the younger generation, what titles they were in and basic team info. 
 

But, of course (because this is me), it got kind of out of hand. I ended up including almost all the students at the Institute (from New Mutants II on), plus NYX, New Warriors (II) & Young X-Men characters. Oh, and Megan Kinney and Layla Miller. Then, I went back and added roomate & (well known) family info where applicable. And backtracked again to add Category (human,mutant,ect.) & Nationality. *grin* That was a good use of three hours.

edit: ah-ha! I remember; I was trying to come up with a list of angry youths!
