I am not a programmer or a computer expert. I am just a "somewhat more informed than average user". I have studied a little C++ programming, but I haven't ever produced any useful code.
I love to recommend Linux Mint to my friends and help them install and use it at home or at work.
As I am more into business management than into programming, I can recommend existing Linux applicatons to friends who want to reduce the cost of their operations, and save them some money.
