The Small Things Challenge is “a year-long effort between Intel, Kiva.org and Save the Children. You can participate by visiting the Small Things Challenge website and clicking the “we’ll donate 25 cents for you” button on the Web site. Intel will donate 25 cents for every person who clicks on the button – up to $75,000 per quarter this year to be split equally between Kiva.org and Save the Children.”
