By the way, I only discovered your original post in this thread with a general Google web search. EMD Forums is spidered often and your great original question was quickly found. Hey, I sure can't remember posts I made a decade ago, so don't think I'm complaining about this question coming up again! If you think about its, it's pretty cool that you answered this question way back then, and now you and the rest of us have the benefit of your old knowledge. We have been hanging around here a very long time - I first posted here in 2004 (13 years ago).
