posted message: Hi group. I'm sorry nobody was able to chat with me today, but I wanted to say how much I've enjoyed facilitating this group. Some of you have made great contributions to the discussion and it's been a real pleasure! I hope you will (if you haven't already) take the final exam to get a sense of how well you've mastered the topics we've covered. And we can continue discussing over the weekend and into early next week if you like. Please follow up with any last-minute questions or comments and we can wrap things up. I'm more than happy to continue discussing with you all!
