Disconnect AOL and get a cable or dsl connection.
Make a folder in your favorite places and tell son that only the site that are in the folder are ones that he can go to. The first time he goes to new site that he must call you to check it first and then can put it into his folder.
Check on the available parent control freeware/shareware out there also. I prefer to closely monitor my son's internet usage (he's 8) but yours may be older.
Good luck - I enjoy my internet much more since I have left AOL and went to cable.
Shattered, I never thought about that. Mozilla has awesome built-in pop-up blocking so I don't really worry about him stumbling across inappropriate pop-ups. It's more about stumbling across an entire website that isn't child friendly. I'll try making a folder for him in Mozilla. I'll have to look into the other parental controls, too...because he can currently get filtered email and IMs from his grandparents, cousins, etc. I'll have to set that up for him somehow.
If you think your son doesn't know how to visit sites that aren't bookmarked in a specific folder, you are in for a rude awakening.
