You folks are all so encouraging! After BobsYourUncle's comment though, that he was rejected by one group because he was fifty years old (and subsequently accepted elsewhere) I though maybe I should mention that I am sixty. ...okay, almost 61.

Is age a problem for a beginner?

I note some slight differences of opinion, but that's helpful too - it builds perspective.

Thanks folks! I'll keep reading as I hear more.
