Comment spam attacks have twice shut down my website, and as such, I've disabled commenting for now, pending figuring out how to keep comment spam robots from overwhelming this site.

Also, I'll be in Mexico from July 29 to Aug. 7, so if you send me email, I probably won't read it until next week, and if you call me, I probably won't return your phone call, as it's expensive to answer calls in foreign countries (thanks, Verizon).
