JFusion is an open and free GPL plugin for Joomla CMS which offers universal user integration and extends support from Joomla 1.5x through 2.5x to Joomla 3 with seamless functionality. It connects Joomla users across versions 1.5-2.5-3.9 seamlessly. Joomla Connect is an invaluable tool for webmasters seeking to integrate their Joomla websites with popular software apps such as phpBB, vBulletin and Invision Power Board.
JFusion makes creating a single sign-on (SSO) system easy, enabling users to log in once and gain access to all their integrated sites with one sign in. Users also benefit from having one centralized user profile where additional information such as profile images, signatures or personal preferences may be stored. In addition to these capabilities, other JFusion features include user group activity synchronization tracking as well as support for multiple languages.
