I have had this link for a while and thought I might share it if it has not been passed around here before. The concept is that you answer vocabulary questions. While you do this advertising is changing on the page. from the money the site makes from the ads you see they will donate 10 grains of rice per correct answer to the UN World Food Program. I just thought this might be nice to share if it has not been already.
