Welcome Elliot,
I cannot answer your questions, but someone will. I just wanted to let you know about the search feature at the top of the page. It is a wealth of information. I also just wanted to mention, that we diesel folk just won our freedom from the fabulous tech help forum. We had a poll to pick a new forum and diesel won. Eventually everyone will start posting diesel questions here instead of the Tech help forum. I think Bill is working on getting us listed right below tech help. Right Bill??? Just kidding.
