I was reading a comment the other day on a website from a concerned parent, who was having problems with her child accessing chat rooms while the parent wasnt present and was asking for some sort of technical solution for this.
As im sure there are some solutions for this problem of a technical nature, i do not belive parents should be relying on these things, parents should not leave their children on the pc alone, they should be supervised, do not rely on a piece of software to monitor your child in chat rooms.
Chat rooms for the most part are safe, but you have to consider that when somone going into a chat room they are potentially inviting countless people into their home.
If you are a parent you need to familarise youself with your pc and take precautions not to let your child use your pc, even if it means confiskating the keyboard, leave the pc in a room where everyone can see the pc and dont let your child have the pc in their room, if they do have access to the pc in their room do not let them have access to the net !!
There are a few ways you can do this the best way to do this is to put a password onto your pc so when the pc starts it asks for a password.
I am off the opinion that children should not use chat rooms , I dont think i would let my children or ducks on chat rooms on the net, but thats just my opinion i have known people who have let their children suft the net safely so it can be done.
