There are a lot of members around here with a sense of humour, who speaks the metric system, and often refers to BAR as pressure, not always as a part in a piece of music. I would guess that there is also quite a few that has played for decades, and know what they are talking about. There is also some people that does experiments and post the results on this forum, as text and pictures as replies to asked questions. Some of these people have also experience as conductors, mechanics and have some first hand experience about how a trumpet is built. Unfortunately there is also some without a sense of humor that takes everything that doesn't fits to their own opinion as a personal insult and yell at the members that ask a fair question according to their own knowledge. No one has ever seen any personal efforted experiments or whatever, but only links to other peoples work when they are refferring to any kind of "scientific stuff". The persons with a sense of humor have never insulted anyone or anything with a language that they could not speak face to face. These same persons does not have "counting posts" as a main hobby. The same persons "gets it", but starts to wonder if there is any use to contribute any more to a forum that is pretty much conducted by control freaked techniques based on dragging other peoples contributions/opinions through the mud!
