Thank you Dr. Rod, you are the first to answer some of my questions. I just want to know how things work. Instead everyone says cut this and use that, but what does it do and how does it work. Like I said, I want to know the terminology to better understand the subject and to know what I'm dealing with. I'm not saying that the other stuff is not what I want or not usefull, I will need it when I figure this stuff out first. I Thank you and everyone who has helped me.
