I am surprised no one has already created a module for this...

I would like a module where you can send donations by paypal and after the donation is complete your name is added to a list where it says when you sent money in, the amount you sent it and the date.

You could also setup little trophy icons for people that send in 20.00, 50.00, 100.00 e.t.c. or define our own rules. I think this would be great for sites looking to get donations
