My university used to send a list of alums from my class who had given, saying it was a proof of the one that would be sent out to everybody and there was still a little time to get my name added to the list. As if that would motivate anyone. I sent back a very calm letter saying that if they ever tried that stunt again I would never give them another dime.
American universities are a really, really dumb focus for anyone's philanthropic efforts.
