AS far as C&C is concerned, I don't have too much to add. Switch the histogram on on your LCD monitor, this will give you an idea on how your shots are exposing and allows you to amend your settings.

On the subject of getting C&C, C&C is not compulsory. People do it in their own time using their own energy. I can promise you that if you constantly complain that no-one is CCing your work all you will succeed in doing is irritating people. I still think it is sad that you not once thanked MTVision who spent hours trying to help you. People will also see your attitude in this thread and be more reluctant to CC as they will wonder whether you will take any notice or lose your rag like you did here.
