  1. Your main page says "cyber-dojo is open sourced on github", yet this license is clearly non-commercial. Please check the Open Source definition and correct your main page.

  2. Hi Unknown
    you are right. I will amend the main page to make it clearer that the license is only for using http:/cyber-dojo.org server
