For sure this an eye opener. I must admit I had not understood the various licences and soon I would have probably found myself on the wrong side of the law. This is the approach that we shall take, in the event that I encounter" great" material that CC ND then we shall distribute to students without modifying as per licence. Those we shall treat as reference material- ie adopting. In the event we adopt material , share I like - we shall repost them as per licence. As we develop we shall hopefully share materials. I have personally share materials in slide share and author stream, some y tube videos, I think I did them under cc I cant remember the other one - I shall revisit them.
