Hi Bob
Fear not we all have to learn until we actually climb into our coffin.
Private Messages are a secure way of us passing info.
I sent you a PM that I would like you to read.
To do this look at the top right corner of the PPRuNe page that you are currently using to read this where you should see a welcome box with your name in it and the date you last visited plus IN BLUE the words Private Messages which are underlined. Put your cursor over the words (which should then change colour) and do a single left click.
This should then get you into your private message log where you will find one from me that you can open and read. In it you will find my normal email address which you should use to answer my message.
