Please be careful with the first link. If possible, refer to the Free Software Directory or to a repository of a free system distribution.
Here is what I found in the Free Software Directory so far (besides Moodle of course): * RosarioSIS (this one is new to the directory, and has built-in Moodle integration): http://directory.fsf.org/wiki/RosarioSIS * ILIAS: http://directory.fsf.org/wiki/Ilias * Claroline: http://directory.fsf.org/wiki/Claroline * TelEduc (developed at UNICAMP, a Brazilian university): http://directory.fsf.org/wiki/TelEduc * Manhali: http://directory.fsf.org/wiki/Manhali * Manhattan Virtual Classroom: http://directory.fsf.org/wiki/Manhattan_Virtual_Classroom * WhiteBoard: http://directory.fsf.org/wiki/WhiteBoard There are others in the directory, but they are "crippleware" (free/libre with limited functionalities compared to the editions with the same program name, from same proprietors (or people endorsed by them) which has more functionalities and is considered non-free unless proven otherwise). Besides, I'm currently waiting for the opinions and voting of a proposal related to this issue with "crippleware but free/libre". The proposal is here: http://directory.fsf.org/wiki/Free_Software_Directory_talk:Requirements
