Dear readers: I just discovered a large number of reader emails incorrectly flagged as spam by my email client’s spam filter. If you wrote to me in October and I haven’t written back, that may be the reason why. If you wrote to me before October and I haven’t written back, I’m afraid your email may have been automatically deleted. I apologize for this and will be more vigilant about watching the spam filter in the future. I hope you’ll write again.
