Good point ,however we have not and will never have your knowledge.We all need someone occasionally to advise us and help out.If that comes at a small price happy to pay.I notice your interest peter cars and fishing.I had a fishing shop for nine years and have had some fantastic cars,but still prepared to get advice before buying a car for a lot of money and spent years helping people to get involved in fishing.The main thing is you have gathered and have the knowledge ,some people are prepared to pay an amount to learn..This can be cost effective weather they are golf ,fishing or coin collecting lessons some of us happy to pay.You use the word muppet and you may no your subject well ,but always remember you dont no everything and sometimes worth a second opinion
