Wow! I just want to say thank you to Mark and Eric, and everyone else for that matter who post such informative and thoughtful responses to questions. I learn so much from this forum. Find myself visiting it every day to see what has been posted. I always hope new images are posted - since I like to see what other people are working on, but posts like this are valuable in the idea and technical sort of way. Again, thanks. Good day.

Never Give Up!
