I just went on to User CP. It does have lots of stuff to look at. I think I had browsed that before, but I didn't know what subscribing to a thread meant. I will have to work on that if I'm ever interested, because when I clicked on it, it wasn't immediately clear how to do it for me!!!! But, I didn't try to figure it out either.
Thanks for the info. I'll have to go back and look closer when I have time.
