Like a few other people here, I took this class recently. I did well, but I don't feel like I truly understand material until I teach it.<p>That being said, if anybody here has questions on the material, I'd love to help you out in some way. Unfortunately, there is no personal messaging feature on HN, so we might have to resort to emails (or maybe a subreddit?).<p>I realize there is an official class forum, so please tell me if you have any interest in some sort of 3rd party support system :-)
