Logging IE 5.0

Is there any way to effectively log websites visited and record the data to a log.
I have a friend who is concerned about sites his daughter visits. In particular he wants to know who she chats with. From what he has described, I am pretty sure she makes use of Java script chats and does not use a particular client.

I am sure that I can manipulate keys in the registry, however: I am not familiar enough with Win 98’s registry to do it. Also the PC I screwed up would not be my own, should I make a mistake.
