Hi!
I saw an article about this on the BBC news website this morning. It's a new website, a state-of-the-art means of doing something real with your social conscience, where you can easily 'earn' Free Rice to be given to the world's hungry, simply by playing a fun vocabulary game! Not only does it enable you to do a good thing for others, it's also self-challenging, and expands your knowledge of vocabulary. Not at all "a waste of time" for anybody concerned! I did it for 20 minutes this morning, 'earned' 1000 grains of rice to be donated, and learned some new words that I never knew, as well! It's easy, fun, and pretty cool! Check it out, give it a try, and if you agree that it's a good thing, pass it on....
Thanks!
