ust when you thought J.K. Rowling couldn't be any more magical, she goes and gets booted from the Forbes list of the World's Billionaires after giving away a huge sum of her earnings to charity. Her charitable donations, coupled with Britain's high tax rates, have cost the author an estimated $160 million (does anyone know the galleon conversion rate on that?). Rowling continues to show up on Forbes' list of powerful women, however, ranking in at number 61.
