A lot of your questions could be answered for you, if you would take the time to read the links that were initially posted. I also posted a copy of the "rules" that serves as a guideline for newcomer LBS. Look on page 4 of your current thread.
The problem is, reading the links, combined with other comments in this thread and on the board, are what confuse me.
Just the last 5 or 6 posts are not clear on this one simple thing, IMO.
