From the About.com MS Blog:Adam's mom came up with an idea that she calls "The Circle of Ten." It is very simple: one person recruits ten people that they know (she wrote a touching letter to do this) to ask ten people from their circle of family and friends to give 10 dollars each. Viola! Pretty soon, you have a thousand dollars.
