Free Rice

Just to get the word out there - everybody should go to www.freerice.com to play a simple and remarkably addicting word game. For every word you correctly match with its meaning, 20 grains of rice are donated through the United Nations to help end world hunger, as the site puts it.

My stats so far (in case others want to compete):

Top level: 42

The total was 2560 grains of rice donated. If this isn't an awesome cause, I don't know what is.
