Suppose I have a program that is used by a lot of devoted friends who have gmail email accounts. Suppose I have a staff that suggests we only sell downloaded software to those customers who DO NOT have gmail email accounts. How long would it take me to fire them? It is truly amazing that the people who make this excellent product cannot figure out how to send such a small program over the Internet, as a great number of suppliers do, so those of us who DO use gmail exclusively can pay them money, and buy their product. I beggars the imagination.
