And don't forget - those of us less knowledgeable - CAN ASK QUESTIONS ! (!) !Amazing concept, I know, *grin*, but true. As has been shown, over and over, if someone doesn't know the answer, someone else will try to find the answer, or at least you get people's curiosity going - which means a larger "work force" trying to find the answer...which (at least in theory) means it will take less time to accomplish.
