My daughter gets easily districted when doing her homework. I'd like to restrict access to certain web sites (e.g., Facebook) during certain times while not blocking Internet access altogether, as there are legitimate uses. I know I can block inappropriate content using parental controls and enforce time restrictions, and there are commercial products like Net Nanny, but so far it looks like they all do about the same thing, and it doesn't look to be what I'm looking for. Anyone have any suggestions? She uses one computer primarily, so the solution could be on that one computer, or it could be something network based. Thanks.
