I got local help from a help desk person at my school. Normally, I have enough students to put them into groups. I thought that this would be true this time around. It turned out that when I made the discussion a group discussion, there was no other team and I couldn't access it. When I unchecked the box for group discussion, I was able to enter the discussion and respond to students, my usual practice. I hated it when I had to be in group discussioins. If I knew enough to generate my own questions for others to answer, I didn't need the class, but the professor never showed up in a discussion. I think that's wrong. If the prof is going to be MIA, then he/she should tell Canvas to give each participant the same score. That's what I think. I refuse to be a faceless online grading machine. Anyway, thatnks for the suggestion.
Best,
Ken
