I know you cannot do much to protect kids from porn materials and other garbage, but I wonder if it were possible

1) to have a regular log of the files downloaded and
2) to protect the filter setting from any modifications.

That way we (adults) could at least have an eye on the use of Limewire and let the kids downloads the songs they want.

Any ideas? help?
I posted this same request in the introduction forum. No reply in weeks. Let's see if Mac users are more supportive/Knowledgable ... (Mac G5 and others +OS10.4.08)

thanks
