I prefer to do things myself too. But if I had received the invitation for this (I have not) I would have signed up to get the bonus points.

OMNI - I'm trying to get to 20K with MyPoints because that is when the 5K bonus kicks in, right now I'm at 12K. 12K Mypoints will get me roughly 12K AA miles, 20K Mypoints will yield 25K AA miles.
