Many thanks for your email, it's much appreciated to receive a personal email after purchasing a product. What I wrote when buying the licence was a very brief summary of how pleased I am with the software, it really has stopped the daily arguments about which of the children has had longest on the computer, and I received little resistance when I told them I was going to install it, it obviously appeals to their sense of fairness. The variety of ways in which access can be controlled, along with the Time Token rewards and alternative settings for school holidays show that you have a very good understanding of the issues! Many thanks for an excellent product, definitely well worth the very reasonable cost.
