Limit the amount of time your kids spend on your PC
DigiParent is a lightweight and easy to use application designed to help parents limit the amount of time their kids spends on the PC.The application can be set to automatically shut down the computer after a user-defined period of time or simply notify the user that the time limit has been reached.
Kids can log back in to the computer after time is done unless you create a separate account for your kids.
Summary
Ever since I started using DigiParent with my kids, I've had way less fight with them about the time they spend on the computer. Its really easy to use. When they want to go on the computer I simply log on for them start up DigiParent and put in the time limit for them and their off the computer shortly after the time is done without going to nag them.
I love DigiParent
