Twice in the last 24 hours, someone has suggested to me that I should check out this site. Not only does it improve your vocabulary, but you get to help feed the hungry just by playing. They donate 20 grains of rice per correct answer to the UN. In under 10 minutes I earned 1000 grains. OH, and I felt really smart while I did it too! :) You should check it out, it's as fun as playing solitaire.
