Moodle is a free online learning management system that was designed to aid on education with a focus on interaction and collaborative construction of content. The program is Open Source and that means that anyone can add or edit features to it. There is a huge community working to solve problems with Moodle and to create a better online learning experience. Check out the Moodle Community page at: https://moodle.org/
