admin,

Its not clear, what do you mean preparing for first discussion topic.

I thought, I have suggested few topics and the group has to choose one of them or add topics of their choice. Finally, we all would agree to discuss one topic at a time (exactly like it happens in a face-to-face GD). And you as ‘admin’ create a new thread for further discussion on that topic. Let’s name this kind of discussion as Virtual Discussion (VD).

I thought this is how it would work. If you have had a different idea, please share.
