You are, of course, entitled to your opinion but this freedom also entitles me to mine and to express myself in any way which is courteous and polite. Since my post is, in my opinion, both I do not understand your problem. If I have inadvertently broken a rule of the forum I apologise and would be grateful to hear which one. I would hate to waste your time so please do not feel obliged to respond on any off-topic subject like courtesy, syntax or lessons in etiquette as none of these is required thank you. For the record the post was placed on a couple of other boards where people with greater experience than me provided useful answers without feeling the need to be pejorative.
