I have only listened to a bit of Lecture 7 so far, and I am so grateful that you responded so quickly via email and phone when I got stuck that I almost feel apologetic.
I am starting to find it interesting, and you have made the lectures so convenient and easy that even someone in the older generation like me can follow along. Occasionally, there are parts where the screen looks different, which I assume is due to the version at the time the lecture was created, but it is still recognizable with a little bit of attention. Since even someone like me without much formal education can follow along, I think it would be very easy for younger people. I think it will get even more fun as I continue with the lectures.
