posted message: In response to Kevin and Sebastien: Thanks for your feedback on the course. Very helpful! Kevin, I wanted to let you know that I'll be available to continue to discuss with you through Wednesday, if you like. (I leave early Thursday for vacation.) Should any or all of you want to do as Sebastien suggested, however, by all means keep going or re-cover the material. In sum: I'll be available to wrap things up through Wednesday, but if you all want to do something more in depth, please feel free to take over and continue the discussion!
