Not real happy with your signature... if you are directing it at all comers you're going to have to be careful what sort of questions you ask yourself, aren't you? A man of your presumably high intellect will appreciate that a question can only be seen as dumb in the light of sufficient knowledge. Failing that knowledge one has no option but to question. Using google is simply the first step in questioning - it brings a list of possible sources. Experience soon teaches that most reliable and rewarding of these sources are forums. Hence one often finishes up in a forum, asking 'dumb questions'.
Thankfully it is very rare - but not at all unknown - that some conceited clot will waste time, space and energy trying to adopt some sort of intellectual high ground and berate the questioner for questioning - while at the same time not providing any answer - when providing the answer would have taken less space, time and energy.
