When replying to a post try to remember that the user has probably tried everything they can think of to solve the problem. That they have come here looking for help and support not to be belittled by someone who knows more about the topic then they do. Forgive them for not having read the forum posting guidelines or for not yet understanding the need for a doctype. The guidelines make it easier for us to help them and for them to help themselves, try to encourage rather then require they are followed.
Think how you would have liked to be treated when you were first visiting. They may have been overwhelmed and confused by the overload of information provided on the web.
Strive to make it a friendly community full of helpful people, so that members keep returning to be helped and to help others.
I'm off to climb a mountain and sit in a cave to meditate for the next few years
