Sorry, to hear about your son's accident.
An observation. I am single. And I have plenty of "free time" compared to others. I wonder if 40 pgs. plus participating in a discussion is too ambitious for the typical OC.netter? Not that I have found the text to be rather "dense", but maybe a smaller slice of reading each week would allow for a more focused look at the text.
Again, I could be wrong. Just noting there was not much discussion activity. Perhaps extending the discussion period for a week after the reading assignment, before moving onto the next reading assignment.
Just some thoughts that could be without ground.
