The NGO charity:water wants to guarantee access to clean drinking water for one billion people – using, amongst other strategies, the chain letter method. In 2012 you could buy a place in the WaterForward book for 10 US-dollars not for yourself but for your friends. WaterForward builds on the belief that some of these friends will in turn feel inspired to buy more of their friends into the book. The first 500 lucky supporters remain on the first page of all future editions of the book. With this innovative fundraising method charity:water has been able to get 30,000 people in the book, thus raising the corresponding 300,000 US-dollars until March 2012.
