I beg to differ. Searching - first this forum, then, if that fails, the World Wide Web - is what you should have done before posting a question. Posting should be the last resort when every effort to find the answer yoursef fails. Not following that is what most people consider "quite rude". That is of course a valid concern but blaming the guy who tried to help you is just bad manners. It's like in that old joke about the guy in the hot air balloon. You are in exactly same situation as you were before but now, somehow, it's someone else's fault. For what it's worth, elros34 has provided a link to the post that you should have found yourself.
