Apologies to all 5 of y'all who are regular readers--and anyone else who might stumble upon this...today's been hectic again, with class, etc.
Might be able to put a reasonable effort later, but right now it's just not possible.
Back then...in the meantime, Tbogg posted a link to Neil Shakespeare's blog, which I took a good long look at last night. If you prefer something equally good, check out Schroeder, who writes People Get Ready. Or HumidHaney, who recently started the Humidbeings forum. Or any of the fine sites on the right hand side of this page.
