Thanks Steve and Jim!

Steve: I was always a little long-winded in such matters, haha. But ... as I said above, I didn't have the heart to cut any of it, so ... :-) Thanks for your kind comments - I'll see what I can do about the boominess.

Jim: thanks! I found it hard to find a title for this, so I'm glad that this one worked. I'm not sure I agree about an introduction, I rather like the abrupt start, haha ... but I'll think about it, as - after some reflection - I may well change my mind! It's a new idea, so it needs settling in my brain before I decide. But thanks for suggesting it and thanks so much for listening for all your other kind comments, too!
