Open apology due here. When liverwort put this thread up, I came down on his questions pretty hard, unneccessarily so. Got a pm from him, he pretty much expressed his displeasure at what I wrote, using "internet muscle" as an apt description of my behavior here, as well as some disparaging remarks about me and my family, which were also unnecesaary to get my attention, but I won't let that stop me from saying I'm sorry for what I wrote, which I took down asap.
It did, however, bring home to me the fact that sometimes I reply too harshly to some perfectly benign things asked here, regardless of how I see them, and I intend to dial that back. Y'all feel free to let me know when I backslide.
This was on my mind.
