1. If you record a program on a non-premium service you must erase it after 45 calendar days. I was completely unaware of this violation. Although it has been years since I taught, many teachers kept copies of taped programs from year to year. I did not know this was a violation.
2. You are not allowed to install a single copy of a program on multiple computers or onto a network without permission. Although I am not guilty of this one (we were just getting one computer in each classroom the last year I was teaching), I think this would be an easy one to violate. I can see where if I bought a terrific biology program, I would want to share it with the other biology teachers. However the Fair Use exception does not cover copying complete computer programs on multiple computers or networks.
