As far as I'm concerned there is no such thing as a stupid question,
although one frequently comes across stupid answers!!! Not that I've come
across many amongst coilers. All of us started by asking questions. Without
a question there can be no answers.
Actually I ask questions all the time, and some very kind-hearted and
patient people on this list and others have helped me no end.
