Naufrago, just remember no one is being paid to answer, it is their kindness and desire to help others that makes people taking their valuable time to answer questions.
a smart comment : wow I see a lot of answers thank you
if no one has yet taken the time, or better, no one with the knowledge needed, to add a cynical comment like this will make people not wanting to invest time in answering your question.
Please and thank you are step one, listening to the advise and taking it is 2, if you don't understand, ask if someone is willing to explain how they came to the conclusion so you can learn and know from that moment onward, and be able to help others.

just trying to explain how I see it, feel free to disagree
