Yes. This seems like a real mess. I had also a course shared with me today by spatterson. The course should have been an entire book with each lesson representing a chapter. I got an email to tell me that the course had been shared with me, but when I followed the link, I had no access to the course at all. Now I can access it, but only because spatterson sent me directly a link to one of the lessons in the course and I am able to get access to the other lessons in the course because I have the little editor pencil. When I click on the little editor pencil, I can see and access the other lessons from the editor page. However, when I open the course itself from the lesson page, I can only see the one lesson that spatterson linked to.
