Thank heavens I had a post already in this thread--that's the one I clicked on; otherwise I'd have been afraid to make this one. I remember the discussion Rapunzel mentioned. I said that, since I don't have response notices mailed to me, it had never occurred to me that anyone would be thinking that I was responding to something they'd said. So now, I do try to click on the one I am responding to. I do not ever go to threaded mode--those titles just go all over the screen, and, Faldage, though I thank you for your explanation then, it just isn't worth it to me to try and make any sense of threaded mode.
But I will also say that I often respond to more than one, per post--I still haven't gotten over remarks about how many posts I've made, and being accused of trying to run my numbers up. And if that bothers somebody, well then, fine, I'll stop posting for a while.
