Help end world hunger

I know that not everyone likes to use their money to help with this cause, but how about playing a game. Go to this link, and for every word you get right, they will donate 20 grains of rice to a needy child. You can look up the words in the dictionary, too. I am including a link to an online dictionary as well. However, you should try to answer what you believe the words to mean. When you do it that way, the words stay more at your vocabulary level. You can play for as long as you want.
