Hi Dave,
I think you have raised some important points on on-line discussion (Elluminate), forum and blogs postings etc. and found them very useful.
I have created a response post on my blog: http://suifaijohnmak.wordpress.com
As I am not registered in your class, I have not fully understood the issues your class is facing. I could only relate to the CCK08 that I have attended, for the sharing of views
What are the general views of students of your class? Are they all different? Is digital identity an issue in your “closed class”?
