fyi re my approval of new posts & my schedule in general, in the event of urgent questions, I will be quasi-available for answering posted questions about the final exam until 8 am tomorrow.
I encourage those of you already approved for posting comments to post your ideas about answers if I leave anyone hanging. The approval process only exists to block spam; I have about 100 spam msgs in the blog queue right now.
