rainy_summer first posted a link to this on her multiply, and I thought it was interesting so I've played a few times whilst I was bored at work (:P). But then I saw news coverage of this a few weeks back on CBS Evening News with Katie Couric, and I was pleased to see that this really works and food was sent to schoolchildren in Africa. I like expanding my vocabulary and what better way than to help others in need whilst I do so? So Play and Feed, y'all!
