This is the newbie board. You asked a newbie question. (One which a lot of oldies don't know the answer too either).

I am the host of the newbie board and there are a number of members who help out with answers to questions from those new to the hobby.  If you don't ask, you won't learn.  Sometimes, you can find answers by doing a search for key words and/or topics and save yourself from asking.

But you should never feel the need to apologize for asking a question on this board.  That's what it's here for.  This is the one board where you can ask without fear of being flamed or ridiculed for it.  If I don't get to answer you, one of my 'highly unpaid assistants' as I call them will answer.  No one of us has all the answers, but between them and me, we will eventually get the word up there on the board.  Those guys are very valuable assets to this board.   BTW, I'm not paid either.  Host is just a title.
