I also know that its not Wikipedia or google…..with due respect whoever u are....I have read the beginners guide....I have joined yesterday so I don't know how to use this website and where to search for notes....this is a very rude way to welcome any of ur new member....instead of those rude and bitter words if u have guided me how to search for notes and how to take advantage from this forum....then this would have been a nice reply....so instead of humiliating the person who is asking for help u should have been helpful
