"Civicboom is an online platform designed to facilitate content-driven organizations and individuals to work together in generating rich media content.
Content-seekers can place a request for specific content. Then, by using the Civicboom mobile app (Android), or by uploading to the plug & go site, a content-creator can respond with rich-media directly to that request.
All incoming rich-media content is then managed by the content-seeker, and directed to a customizable plugin to be embedded on a website."
