Classes 4 Classes

So, I'm just sitting here on my spring break watching ABC World News.  {I know, it doesn't sound too exciting, but it's nice to not have anything that must be done.}  Anyways, a teacher from Sandy Hook Elementary was featured tonight for a new website that she just started up called Classes 4 Classes.  It's all about kids paying if forward.  She came up with the idea after people from around the world showered her students with gifts after the December tragedy.  I think it'd be a great classroom project and a wonderful life lesson.  Has anyone else heard of this website?
