Hello, this question is asked several times a day.. lol
Many people here do know and are willing to help..
Problem is, it is frustrating when someone takes the time to answer and help these questions and then someone else posts the same question right above it instead of doing a simple search to find all the others that contain so much helpfull information..
look through and you will find MANY posts just like yours with TONS of information and links to websites that will answer just about every question you can think of!
just my $.02
thanks
