I'm not trying to scold you, but everything you asked in this thread could have been answered just by reading the FAQ. From now on, surf them to see if they contain the answers, and if you can't find them, try searching.
I try to be as nice as possible to new members because this site is extremely helpful and a very friendly community as well, the more new members we can draw in and keep the longer lasting and more prolific the site will be. However, you must understand how frustrating it can be to see questions asked a million times when the information is readily available, and even stickied so it can never be buried. Finally, please remember bandwidth is not free, but this site is and we don't even have advertisers to clutter up your screen, when there are threads posted with information already posted it's a waste of bandwidth.
