I've got a friend with two kids that tend to do nothing but sit on the computer from the time they get home from school until they go to bed. She is not always there to enforce who can get on and when, so she had me set up the time limits using the Parental Controls.
While this option is a great way to limit one person's time on the computer, it doesn't seem to be working out as we'd like it to because of there being two children in the family. We're looking for something more along the lines of giving them the ability to be on the computer for say 2 hours at most between the hours of 3pm and 9pm on school days, rather than unlimited time between those same hours.
Any help with this is greatly appreciated.
