Wow I've learned a lot from that! I think you should write a book if you have not already. I'll happily read it. I agree with everything I have read from your post, however, I'm going to copy and paste it so I can read it again when I'm not so busy and take in every point. Looks like I need to reconsider a couple of ideas. This to me is Mudcat at its best. Thanks for taking the time and trouble, that must have taken a while.
