im not having a pop but, my kids arent quite 11 yet but i NEVER let them on the computer alone anyway (no telling what theyd delete or who theyd talk to). i think its a bit much to expect a leave if under 18 notice and all that as you signed up and you registered as a member, so you cant really expect the mods to controll what happens at your end. it is after all an information forum.
before i updated from 98, me, the missus and the kids had seperate folders in the favourite folder. as narabdela says, xp now is fully personal for the signed in person, you can log out and stay connected to the hub,etc and 'most' members put ADULT before any posts that may be. that way your favourite sites are only available to you
