[Air-l] Any good Free E-Learning Platforms out there?

Hi, All I am trying to find a good Platform (e.g. something similar to Blackboard or E-Courses) that will enable me to deliver online courses free of cost. Is there such a platform? My training institution is small and can not really afford to subscribe to turnitin etc. thank you very much for your help, Michael Baron -- "My Body is my Temple" "Be The Change You Want to See In The World."
