Thanks for the welcome, StoneWall! My bad on my initial post; I guess I'm still being too much of a literalist even tho I'm going in the scientific explanation direction now. Besides, I apparently didn't read all of your post carefully before I started slinging words and script. Can anyone tell me when I can be a 'real' member, 'cause I apparently am not able to access my account and put a photo on that will show up with my name, etc., etc. But I'm looking forward to being very active on this site!
