Just in case anyone is still thinking about eLearning or Learning Management Systems here's an interview with the creator of Moodle:
http://www.edugeekjournal.com/2010/10/18/is-moodle-going-down-the-path-of-open-social-learning/ Worth noting that he's considering a complete rewrite focuesed round the learner rather than the course. Also ofnote is that the moodle.org support forums have over 1 million registered users! (http://moodle.org/stats/) Although on the surface this kind of application seems simple, I have recently been grading my students using the Moodle gradebook system and have been reminded how much complexity there is in just that small part of the system - nothing you wouldn't be able to get you head round over breakfast though Massimo ;-)
