I don't know if this will help or not...But I have a password that I have to use to sign on to my ISP. It is never saved. So, when my (teens) want to get on, I have to sign them on, and when I have to leave, they are off. Been rule from day one, and they have never questioned it..Just the way it is....(Of course, if your kids don't know what "Ctrl H" is, that is a good way to find out too, where they have been.
There ARE those programs,,,have seen them at Staples...for the most part, when they know that I am here, and watching, seems to be good so far...
