Fore the benefit of people searching the mailing list archives for answers to similar questions, please only ask ONE question with an appropriate Subject. You are also much more likely for some one to respond with an actual answer. The way you are currently asking, I doubt you will get much help. BTW, did YOU search the mailing list archive first for these answers? I have found they answer nearly any question I have.
