Online giving course starts today; Warren Buffett and other heavyweights will teach students to give away money (starting with $100K of his sister's funds).

"A free online course that starts Monday will offer students the chance to learn about giving from Warren Buffett and help decide how to spend more than $100,000 of his sister’s money. More than 4,000 people have already signed up for the course that will also feature philanthropic advice from baseball legend Cal Ripken Jr. and the founders of Ben & Jerry’s ice cream, Ben Cohen and Jerry Greenfield. Boston Red Sox Chairman Tom Werner and journalist Soledad O’Brien are other featured guests. The amount being given away could grow if more students sign up." -- Associated Press
