BCBird, I appreciate your taking the time to answer this. It's not an important question really, because I'm not especially interested in the number of posts I make. Maybe I'm missing something obvious but it surprised me to notice that I posted once (say at 5 pm, just an example) and it showed, say, 170 posts. Then I posted again further down the same page and it still showed 170. As I say, it was a surprise that I didn't understand (still don't really!). I suspect some of these things will make more sense to me as I continue to participate in the forum.
