I'm afraid i found some of the responses to a simple question were plain rude.
I rather got the impression of the writers gleefully snorting as they put 'the noob' in his place.
The explanations of too many people asking boneheaded questions which stir up trouble doesn't hold water either.
The OP asked his question in the Spotters forum. He didnt enter the hallowed ground of any of the professional pages.
Get over yourselves.
