Improve your Vocabulary

This was in Time's Greatest Websites list.
I've been hitting it everyday for 15 minutes or so,,

It's called Free Rice, it's simple, for every word you get right, the sponsers donate rice. If the words aren't tough enough for you there is an option button at the top of the page, there you can increase the level to suit your vocabulary, it also retests you on words you get wrong, top score is 60, I reached 40 (so far), give it a look :cool
