Thanks everyone! I went in a changed the parental controls - I had forgotten they were there in the prefs. It's his computer and he could change them, if he knew about them, but since he doesn't.... We had briefly discussed the issue and so I just told him that he actually won't be able to download any adult rated shows or explicit music because he's underage. He figured it was because he had put his birthdate when he registered his computer. I'll just keep letting him think that for now. I know there's lots of other inappropriate stuff on the net that he can get into but for the most part, I am able to keep a fairly close eye on what he does. It's a bit harder with the ipod because he can download stuff and sync it and it's not so easy for me to see.
