Gerry and others,

www.MacForTheBlind.com

Has several mac and IOS tutorials and one is specifically on email.  John 
does a great job in his digital audio Mac tutorials.  I'd be glad to share 
what I know about it, Gerry, but John's tutorials are first class and he is 
also an authorized Apple tech support type guy and really knows Apple 
products and their usage.

The KX3 is pretty cool.  I did not know that about the Icom 7000 and the ham 
pod, but I did know N4PY has software that works with the 7000.

I certainly understand the frustration with getting started with any new 
phone or product but that tutorials are really great and he is adding to 
them frequently.

Phil.
K0NX
