I know that you are new here so I will be nice. A lot of the questions you are asking can be found by doing a search here in the forum. Also, a lot of the answers you seek are already compiled in the "mod thread" at the top of this forum.
Please do a search for all your questions before making a bunch of threads that really dont explain much.
I am afraid that if you keep up your rate of posting most of the things you post will end up getting locked and/or moved to the correct forum.
