Absolutely Brilliant! Rated 4 out of 5 stars

Seriously this thing has helped me get my studies back on track, I used to waste a ton of time on forums and the like but now I have an extra layer of conscience to wrestle with (x64).
Plus my other siblings have also stopped using the computer for gaming as much now. The only thing that would make this perfect would be as Niall Jackson suggested a white list to block harmful sites.
Great work keep it up!
