Not being a technical gal, I can't be positive, but I can tell you what I think is going on....
I've noticed that if someone doesn't post for maybe two weeks, all their latest posts disappear from the "In Forum" page, and it just says "no posts".
I think what happened is that Daus didn't post for a while, then began posting again, so his posts started over with the first one after the absence, and when you, Jeff, started counting, there were only 40 there.
Of course, I could be wrong.
You may well be right. Daus has made more posts since I counted the 40 and now there are more than 40 posts there to be seen. The same could well be true of the other people for whom I have noticed this phenomonon. I will investigate further.
Thank you for your astute observations.
