I have joined discourse for discussion with peers and mentors.
But I think it will be helpful, if in the discouse we have sub forums for week-1, week-2 , etc as in the coursera forum. It will help us in sorting out the doubts for each weeks and also having separate forums for each week also helps in better discussion and better analysis of concepts.
The course is wonderful and active participation by mentors and peers make the course enjoyable.
