It seems very simple if you just think about it... If someone has a question, they can ask it on this forum. If someone has an answer, they can either provide it, or they can ignore the question and move on. Instead, some people choose to provide condescending answers ("I'm your father, go do your research and go to bed") and waste everyone's time with non-answers. Why do that? Just answer the question or don't answer the question. Seems so simple...
We should aim to help each other on this information forum if people have honest questions. Pprune can be like Google - so much information that the relevant bits are actually difficult to find (just look at the size of this thread - 130+ pages). Just answer the dang question if you have the answer or move on.
Everyone have a great day.
