First, an item of late news:

I have been unable to write or work at much of anything for several weeks, because (as it turns out) my thyroid gland has gone walkabout. So I spend an average of about 16 hours per day sleeping, and the rest in a waking fog, whilst my thyroid schleps about the Northern Territory, communing with kangaroos, dodging crocodiles, and pretending to be Paul Hogan with very little success. At least it hasn’t been eaten yet. Medication is forthcoming once tests have been completed and results resultivated.

In the meantime, allow me to remind you all of Unbreakable Rule #5 of Good SF, courtesy of Reginald Pikedevant:

This is old information, but apparently there are some benighted souls who have not yet received the news. Spread the word! And remember, there may be a quiz on this later in the term.
