In 2012, the MCSC successfully launched the first-ever online search party, the World's Most Valuable Social Network. The organization now had a way to alert the masses, but also wanted to reach those most likely to report a sighting: people nearest to the place where an abduction occurs. So we created the World's Most Valuable Check-In, a digital tool that sends alerts to nearby FourSquare locations when a child goes missing. As one of the MCSC's new digital tools, Most Valuable Check-In is directly responsible for assisting in the rescue of six children in the first five months alone.
