As an computer engineer Chamilo is easy to install and has a very low RAM and CPU consumption. As an LMS administrator, no configuration is needed to start using the platform, integration with an existing information system is easy. If needed, you can activate or modify many options to fit your teachers' needs better. As a teacher, you need a short traning to use the platform. Tool usage is intuitive, and when you get used to them, you can start using the learning path tool to put your course into an educational sequence. In a third step, click on Advanced tool prorperties to improve your Chamilo experience. Teachers can use the platform gradually without being lost. Students don't need training. It's really an advantage when you have several thousands of students using your platforms, with new students every years. [warning, technical speaking here ;) ] If you are a web developper, you'll really apreciate the use of the newest develloping tehcnology in Chamilo. Chamilo uses Silex components of the PHP Symfony framework (which is, of course, open sources too)... and it is just great. This is a guarantee of security, resistance, flexibility and easier coding contribution to Chamilo.

The user experience is very nice : I'm not wasting my time improving this, out of the box the user experience is really good. I appreciate a lot the Human Resources Management features of Chamilo, the Skills wheel is really very useful and nice : it's easy to see who has what skills in the organisation. Other point that I really appreciate is that the project is driven by a non-profit association, and that Chamilo is really open source, there isn't any parts that are non open source. We have here the same spirit that there is Drupal for example. I also really appreciate the Scorm integration contents. It's very clean, while in other open source LMS it's not so visually clean, or not so ergonomic.

from the very beginning, this open source platform is awesome. Easy to install and configure, Also very User-Friendly. You have tons of Authoring tools to create your own content and the BBB (Big Blue Button) video conference integration is superb.
