I agree with you Jim – too often the answers aren’t given thanks, which is a shame, but seems to be a way of the (internet) world these days.
I would like to add one request, though, to you and all other responders – please don’t let those “bad apples” (if one could characterise them thus) dishearten you into stopping your valuable contributions – that would be but another flavour of what’s been going on elsewhere here recently.
