I have reached the point in my life where I want to rent an 8-12 year old to help me with my phone, computer and other electronic items in my world. I found something almost as good, and available on demand.
Look at the website TeachParentsTech.org. They have many short 1-2 minute videos to show you how to do simple things on your PC or Mac computer. My first lesson was how to make the computer screen print bigger! Yeah! Now I can see the print without squinting or trying to change the lighting or angle of my screen.
A grand side effect is the series of enthusiastic young people clearly explaining in simple ways some of the many mysteries of technology. They make me optimistic about the future.
