I'm not a girl.
BUT I think the idea is a very good one. I think it would be really
cool if everyone in the group put up some money, you know? I had a
competition between a girl and I to lose 6%. We each put up around 80
a piece so it makes a good pot. With 12 or so of you, that would be
one sweet pot at the end of the challenge, and nothing makes people
want to win more than money :)
