To enhance the interactive learning features of your platform and add a social learning dimension consider adding the following features: Discussion / Forums tool for class questions and assignments Pages feature for reference information and class specific documents See an example of how I've used this on Ning to create a distance learning social space that also integrates with Proprofs: http://bid-to-win.ning.com/group/apmp-foundation-and-exam Currently I use Ning pages as a common content for the ProProfs course. With the above features in ProProfs I probably wouldn't need Ning.
