I'm going to go out on a limb and guess that, being unsure, the OP came to a forum on which members probably know this stuff and inquired so that he could learn.
It makes me want to go back to that thread from a month or so ago wherein so many of our members just could not understand why so many other members do not wish to start their own threads.
My guess is that it's the inadvertent exposure to unexpected ridicule that makes people not ask questions that could save them a lot of wasted time, money and heartache.
I'm just thinking out loud here.
