Responsive / Social / Web is a passion project of ours to reinvent social giving by giving back to donors.  The site is WordPress based with a custom engine for handling campaigns and accepting donations. It has a built in Facebook app integration that allows clients to bring people in to participate in the campaigns directly from their fan pages and has huge social integration via the Social Wave functionality that allows donors to donate their social voice in exchange for a chance to win a once-in-a-lifetime prize.
