The i’m™ Initiative from Windows Live Messenger™ makes helping your favorite cause as easy as sending an instant message.

Every time you start a conversation using i’m, they share a portion of their advertising revenue with some of the world's most effective social cause organizations.

Each of their partners will get a minimum of $100,000. As for the maximum? There is none. The sky's the limit.
