Well it's working so far. And scumbags did not refer to people posting here. Incidentally, I haven't got time to do all the processing required to comprehend your point about your quote from my post, etc. You do have this somewhat enigmatic man-o'-few-words way of putting things at times that defeats me unless I do about ten minutes' hard labour. Just thought I'd mention it. I have tunes to play on Fridays, you know.
