SocialVibe

I found this site today. It's called SocialVibe.com. With this site you can do amazing things. All you have to do is sign up, then you get pick out a charity. (There are only a handful of them so choose wisely) The charity you pick out, you actually get to help raise money for it, just by posting a "badge" on your favorite social networking sites. Once you pick your charity, you're taken to a page in which you pick out your sponsor.
I signed up, I'm supporting the Leukemia and Lymphoma Society and Adobe, the software giant, is sponsoring me. From just signing up I've already raised more than $2000! It's crazy! I'm really excited about this. You should join too.

[I realized later that I, myself had not raised that much. That's how much everyone together on the site had helped raise. I also no longer have Adobe sponsoring me. My new sponsors are Hello Kitty and Converse]
