Dude, I caught on pretty quick what it is that you were trying to accomplish. It's kind of a road map, and lots of time, what you are looking for is right under your nose. Ha Ha Ha... I have always gone by the philosophy that there is no such thing as a silly or stupid question. To take the time to ask a question shows intellect and intelligence, or as I prefer to call your kind, "our" kind... we are survivors. Keep pursuing information. Don't forget young grasshopper, the one thing that can never be taken away from you is education, and knowledge is power... keep asking questions.
Stay safe buddy and remember, JUST DO IT!
