Being able to set up what time of the day, how many hours of the day or if the user can be on at all has made a great deal of difference in my house. I set up the program to stop the user at a specific time and he gets a 5 min warning and is then logged off on time. When I tried to circumvent the program, I couldn't change anything without the administrator password and I could not change the computer time to trick the program. This has made a big difference in not having to spend the energy to nag or being seen as a nag to get him off the computer instead of him playing till 2am.
