Given the complexity of the subject and the public nature, I might suggest that they consider using the opensource and free Hypothes.is platform as an academic discussion tool for allowing everyone to highlight, annotate, and respond to the text and conversations?
I suspect the Hypothesis team would be happy to do a quick run through of their platform as well as potentially creating a private group if they preferred.
Funny enough I just recommended this past week that @Marketplace try @hypothes_is for their virtual reading group.
