Deborah,
admin of WONDERLANDS, did a notably post on 9th of January 2009.

This is the text of her posting:
"Hey Wonderlanders - what if just knowing what a word meant could help feed hungry people around the world?

Well, at website called Free Rice it does.
Go to the site, and you'll see a word and four definitions. Choose the right meaning and the site's advertisers will donate 10 grains of rice to the World Food Program, a United Nations agency that is the world's largest humanitarian organization. Keep on guessing (the quiz gets progressively more arduous, not to mention vexatious), and for each correct answer 10 more grains of rice will head to people who need it. Now, admittedly, 10 grains is a piddling amount. But the totals have grown exponentially. Over 56 billion grains of rice have been donated to date through this innovative program....

I must warn you though, it's somewhat diverting and compulsive for all us word-geeks!
