Now I know why newbies do not get to start new threads at Thunder's Place. They dont get to ask a question that has been asked and answered so many times. This question has been answered here, like 3 times this week alone.
Not to sound like an ass, but do some research BEFORE you ask a question. The PE section does not get as much traffic as some of the other forums here. You will not get lost. And you may run into something or discover something new along you way.
