Tracy, a funny thing just happened. I replied to your last post in the thread about photographers and web sites. I changed the title to reflect the fact that I was bringing up a new topic. When I was done, I didn't see my reply. I navigated to the top of the messages, and saw that my reply had been made the first post in a brand new thread. I guess the software looks at the titles to decide what thread things go in.
I've never seen that before. I won't be changing titles so cavalierly any more.
