I’ve mentioned this particular piece of software before on my old blog. This has been one of my best purchases as a parent. Computer Time allows you to set time limits for your kids, so that you don’t have to argue with them when their time is up. You can set limits according to the time of day, and the number of hours they are allowed on the computer.
The interface is very easy to use, and I was up and running in no time. One way we use it in our house is to have a “school” account, and individual accounts for each family member. That way the computer is available during the school day for only just enough time for her to complete her schoolwork, and discourages fooling around. Her “free” time doesn’t start until after school hours. We’ve had it for over a year and it’s cut down on the arguing a LOT.
