Thank you very much for posting the link. The information there sure answers a lot of questions I've had. Maybe someday I'll be able to put this information to use. I'm hoping so.

In the first post at the link are a couple of jpeg image links. I can't see the images on my screen. When I click the links a message says I must be a member to view them. What do the pics show? Would it be worth becoming a member there just to see the images?
