Chamilo support for Nanogong continues and is improved in Chamilo 1.9 (I do). Julio Montoya has improved it too adding audio exercises. So if Moodle is declining and with danger of privatization (Blackboard buy Moodlerooms and NetSpot), we have to do is acclaim the Chamilo different way, and do not bear the others have done.
Not only Nanogong improvement, but also extending the audio tools, with the addition of a open source tape recorder on flash, but does not need a dedicated server (I do). This recorder allows much more compatible files and of course now it has only Chamilo. Hopefully when Blackboard or Moodle to copy not forget who made the innovation.
Free software, live in freedom
Long live Chamilo
