And don't make these kind of stupid threads where you ask something simple. There is 100% chance of finding a tutorial to all of your problems you listed so far.
dude, really? I'm sure there is but there is no need to be so offensive and immature you could of easily said, "If you want a quick answer you can use google to help you out, there's all kinds of information. on what you listed."
anyways thanks hotgreen I'll try it out and thanks for the link for the ttt stuff and the video mehis.
