I just want to say thank you for taking yourself out of the applicant pool to the other schools now that you know where you are going. I think some people just want to see if they can get in places and don't consider that they are actually taking someone else's spot by not telling the school that they will not be coming.
Does withdrawing do anything for you? Or does it just let other schools know that you're fabulous and they need to keep their hands off?
Correct me if I'm wrong, but don't quite a few schools (at least the one's I applied to ED) have non-binding early decision?
