Thank you for your posts. whether you believe it or not the forum is a two way street. You are using it as a two way street. the fact that it is not responding to your prompts in the manner that you expect or desire is not the fault of the forum, the contributors or the users of the forum. It is just that you haven't tweaked the right buttons.

Reading the old posts every now and again an odd contributors fronts up with something out of the left field which is of benefit to all. There are also contributors that lurked in the background for six months or more before coming a contributing member. Some out there just need nuturing and a bit of coaxing. You are searching for that elusive angle that is easy to select has a high strike rate with excellent dividends. That angle has to come from a different area of thinking. Better prompting without the armthrowing may produce this and it may be shared. Or the person who has that secret angle may twig that he or she has something and say "why should I share because all I got was bagged for learning".

Please keep prompting at least for your own sake a good percentage of what you post is educational to others and some no doubt educational to yourself.
