I too enjoy reading the comments of other students on these courses: a lot of people are incredibly knowledgeable and are happy share their thoughts/experiences/knowledge, which beautifully augments the course content.
I remember when we were doing the England in the Time of Richard III course with FL, I happened to discover that my ancestors came from a village in County Durham owned by Cecily Neville, Richard III's mother. When Richard travelled to London to claim the throne, many of the men from the village accompanied him. It was exciting enough for me to have discovered that, but even more so because of the timing, which meant I was able to share something of relevance to the course with my fellow students.
That is in my opinion one of the strengths of these courses: it's not just the course content which is important but also the role played by the students.
