A useful, easy-to-use course management system. Moodle allows users to create courses and social communities, and maintain them with ease.

Modified from "Martin Dougiamas"
Moodle was the product of Martin Dougiamas, a former webmaster of Curtin University. The project began in 1999 because of Dougiamas' "frustration with the existing commericial software at the time". Moodle is used by over 10,000 sites with a large developer community contributing a large amount of features.
