[ADDENDUM: I apologize for the multiple edits and also for the one that, unintentionally, transplanted part of @greg.smith’s post into the middle of my text!]
I’m quoting myself in a new post, here, to try to draw back some readers I may have lost when Greg’s text showed up in the middle of mine. I apologize that it takes me so many edits to get a piece right, but I find that the Discourse text editor is very hard-to-read and finicky sometimes - nothing to do with my advancing years!
