Never once did I take a course in how to use a computer. I cannot write a line of programming. I just use my computer to find information, share email, draft documents, store pictures, and socialize both here and on Facebook. I have no music files to speak of. And, I have no idea what Instagram is. Could someone help me on that latter department? What is it, what is it for, and how do you use it? What difference does it make in your life, assuming it makes one? Thanks.
