Thanks for your response. I am 57 years old and will soon need to find something to do in my spare time. There are so many sites on the Web to learn App building. I would not know where to start. Each site has its way of learning and say that their's is the best. Have you heard of any sites that, with your knowledge, would suit me?
I am not taking it lightly: Maybe I was being a bit lighthearted, but I am serious. You know, one never knows where life will take you.
