I can't help you with the answer to your question becuase I need the answer as much as you do (though I am quite happy to use a capo)
But, I think you asked a great question in an intelligent way - most respondents have recognised your good intention in asking it and have responded helpfully. You also show great foresight in saying you will ignore any rude responses because, unfortunately, some respondents can't take a perfectly reasonable question like this at face value and have to resort to being a smart-alec. I mean you Braindrain - just what does your sarcastic reply add to this lady's knowledge? Not much about music theory, that's for sure, but a whole lot about you.
