I spent the past month trying to get Ubuntu working on my dad's friend's laptop, and managed to get everything except DVDs to work. Today, I got a "thank you" card from him with a $100 check in it.
I don't feel right taking this money (Ubuntu is free and he didn't hire me to do it), but he refuses to take the money back.
So, how can I donate it to Ubuntu's development?
More specifically, could I donate it to Ubuntu's aesthetic development? Maybe there could be a contest for the best new default theme, and the money could be the prize?
I've looked on the Ubuntu site and I can't find any "donate" links or anything.
