It helps to scroll down the screen to see all sections of the forum, not just stopping at Newbies Corner and "Ah, let's smack my question right in here." It is a good thing to suspect that everything that you are asking for has been asked already - and answered as well. The search tool will help you to locate the information. Certain questions are asked very often ... or let's say frequently. So many websites (and CS is not an exception here) will maintain a list of such Frequently Asked Questions.
