We need a bug-free installation of the Joomla and Moodle bridge found here: [login to view URL]
The bridge has been giving people many problems. Proposed fixes and workarounds are posted in the Joomla forums [login to view URL] and [login to view URL]
The working bridge wraps the Moodle install in a Joomla wrapper and passes user information from one application to another.
We are currently using the SMF forums/Joomla login module and bridge as well.
Please post links to other Joomla project you have completed.
