The tasks and links to all resources are coming later today. We will change the payment system next time around, so that it automatically mails files to people. Quite a few people miss the download link in the current system. Thank you for letting us know about problems, and for supporting the course and our cause!
I am not finding the course either, except for the introduction questions. I think it is supposed to start today. I have been getting email updates to the introduction questions and I saw a reference to being given 12 models for multiplication upon registering. I haven't seen these.
I am eagerly looking forward to this class.
