vocab fun to feed the hungry!

I just learned of a great website run by a nonprofit. Take a little vocab test and for each word you get right the advertisers on the page donate 20 grains of rice (well, the money to buy 20 grains of rice) to the United Nations World Food Program. As you get words right they get harder, when you get them wrong they get easier, its a fun little vocab improving way to donate money to the WFP!
