Gahi..... Have you checked the other posts on this subject. There are 6 other than this one that showed up with a quick search. They should answer your questions, or atleast give you some different ones to ask.
That was why I posted the link to the one post. We do have a good search engine. If it is used properly, you can save alot of time and get more answers to the questions you have.
