That's a funny one Allengraph. But the idea of Allen9 is not that bad. But he's right on something, would people read it, maybe a bunch but not all. But for each challenge made repeating the rule would be a good choice since we never repeat enought. I know what i mean since i am doing it each day to peoples who the information goes in and out at the same time. But i mean no disrespect to any body. Pleiades
