Notes:

• Reading assignment and group discussion are separate items
• I created a short code for the virtues list, so we can easily place that list on any page and any edits to the list will affect all the pages where it appears.
• I removed some of the scaffolding for the assignment questions.
• I numbered the questions to be answered. I think this makes it easier to locate them (and to avoid missing one).
