In honor of the upcoming Thanksgiving holiday in the U.S., I thought I'd post a couple of links to benefit those less fortunate (snopes.com says both are legit!):
The Hunger Site gives free food daily if you click a button on their website. Mercy Corps and Feeding America distribute the food to those in need.
Free Rice gives 20 grains of rice through the UN World Food Program for every question that you answer correctly on topics ranging from vocabulary to math, geography, and chemistry. (I liked playing the games on this site; I donated 1,460 grains of rice!)
