Is it possible to integrate all three without major php code changes? I have seen successful integrations of amember+Joomla, amember+Moodle and Joomla+Moodle (with Moodle within a Joomla wrapper). I would like to integrate all three with a stipped down Joomla as the front-end website, amember handling all subcriptions to courses, Moodle as the LMS for the courses.
