JFusion is a free GPL Extension for the award winning Content Management System (CMS) Joomla. JFusion provides universal user integration, by extending the Joomla 1.5 user authentication framework without any core hacks.
With JFusion your users can login to both Joomla and the software(s) integrated by JFusion using the same username/password. No core hacks are made to either Joomla or the integrated software(s) which has the advantage that your can upgrade your software normally without reconfiguring JFusion.
JFusion also comes with a latest activity module, that displays the latest activity on the forum in Joomla and a login module that displays the forum avatar in a Joomla login module. As development continues, we hope to a search module, a who's online module and a discussion bot.
