Hello. My elder son spends all his free time at the computer! He is fully obsessed with this infernal machine. He doesn't want to discuss it and gets irritated every time I try to talk. I decided I have to use the same weapon against this habit - technology. There are some programs you can use to control someone's computer activity, right? I googled some, but would like to hear the opinion of someone who already did or does it. Thanks in advance.
