On the off chance you haven't heard about freerice.com, I thought I'd tell you. It's a website where you can play a game that tests your vocabulary. For every question you get right, 20 grains of rice are donated to the United Nations World Food Programme to help fight hunger and starvation around the world. (The rice is paid for with money from companies who advertise on the site.) If you get a question wrong, the game isn't over -- your next question is just easier, and you can go on donating and improving your vocabulary.
The site was created by a guy named John Breen, who also created thehungersite.com, another site where you can contribute to worthy causes just by clicking on a button. Since it launched on October 7, freerice.com has donated more than 7 billion grains of rice.
I like situations where everyone wins, and this seems to be one of them. Companies get exposure, visitors get learning and fun, and hungry people get food.
Jesus said that whatever we do for the least of His brethren, we do for Him (Matthew 25:40). So if you've got some time to kill, check out freerice.com and help feed some hungry people, and Jesus.
