Points of order, folk ..
(a) this forum is not just for those with a gazillion hours, engineering experts, etc, etc ....
(b) if a new chum asks a simple tech-related question it stays and, hopefully, gets answered appropriately, even if that answer is a link to an existing thread. It is a reasonable presumption that, for every question asked, there probably were several other posters who didn't ask the question for whatever reason .. In any case, our view is that the only dumb questions are those which don't get asked ...
(c) if a poster appears to have some difficulty with English then we extend him/her the courtesy of making that little bit of effort which may be necessary to accommodate the difficulty.
(d) the posts deleted are not pertinent to the basic thread.
