JFusion is a free GPL plugin 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.
JFusion will force Joomla to use an exteral software as the "master" of usermanagement. This has the advantage that users can login to both Joomla the software integrated by JFusion using the same username/password. No core hacks are made which has the advantage that your can upgrade your softwares normally without reconfiguring JFusion.
JFusion also comes with an 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.
JFusion does not have bi-directional user-sync at ths stage, which makes it unsuitable for people with a large Joomla user database, to extend their Joomla installation with a forum (we are working on this feature at the moment
Also, Fusion is an alpha release, intended to get feedback from the Joomla community. JFusion should not be used on production sites at this stage.
