1. We aim to build helpful, friendly community around Lift. Be polite. Please say please and thank you. No coarse language.
2. Even if expressing critique be constructive, respect others, respect great work done so far.
3. Demanding immediate answer is bad. In subject describe the problem, don't put 'urgent' or similar words there, avoid them in your message. We do read messages and answer 99% of questions pretty fast, for free. Sometimes knowlegable person may be busy or away, question may be vague or requires lots of work. Try to refine it, prepare working example, try to make step towards resolving it yourself. Don't bump unless no response for more than week. If you can't wait, consider hiring paid consultant.
