This is without a doubt the BEST non-commercial extension I have had the pleasure of coming across. In fact I would go as far as saying that this comes close to knocking a lot of commercial extensions off their perch. If the Developer charged for this, I'd be first in the queue, cash at the ready. If you want to integrate Moodle into your Joomla site,look nowhere else - this is the only extension you'll need. The extension is backed up by solid,easy to read documentation and a forum with a lightning quick response. I can only presume that people not giving this full marks didn't have the patience to sort out the minor installation quirk which is easily rectified by running an SQL command in your Moodle database - I have NO MySQL experience but by folloing Antonio's clear instructions (he even lays out the SQL command for you!) the installation was up in no time.Every credit and hats off to Antonio and his team for a world class Joomla extension!!!
