Hello all, thank you for your helpful feedback on the course, I've been doing my best, for the last 5 days or so, to plan ways of responding to your concerns, and I'm hoping the course will be better as a result. So that you know what I'm doing, I've re-typed some of your concerns about the class and described them in what I hope will be a helpful summary.

I hope you'll take the time to look at these, and then make additional comments here, as you wish. In the posts that follow, I'll respond to a couple concerns in ways that seem important -- please feel free to continue the dialog here.
