another in previous posts. It may be frustrating for you to be told to use "search" to find quick answers to your questions, but several hours of reading will bring you up to speed with your Z ownership and will benefit you more in the long run. It's like asking your parents/teacher how to spell a word and they tell you to look it up in the dictionary. If you look it up, you will own it & understand it. It will be part of your knowledge base rather than just be something you were "told".
