Pligg was created as a social networking CMS. While most content management systems are designed for only a handful of authors, Pligg CMS was designed to manage a site with an unlimited number of authors. All of these registered users are in control of the website's content. The application itself is a user driven CMS that relies on the content of independent authors and participation to manage news articles.
Pligg started as a simple CMS to let users submit and vote on news articles, and that is still what this application does best. Vote on stories that interest you and articles that receive enough votes will appear on the homepage of your Pligg site. Pligg offers a 5 star system for voting or the more traditional numbered voting as seen on sites like Digg, Mixx, or Reddit.
