We just had a guest speaker at our church this past Sunday to address the importance of parental control over the internet, so I have some good recommendations for you! He suggested using both an Internet filter and an accountability program. Here is what he suggested:
K9WebProtection.com (free internet filter)
X3Watch.com (free accountability program)
- OR-
SafeEyes ($40 per year subscriptioin, but it's a little more sophisticated that the previous two and combines both the internet filter and the accountability program)
Good luck - it's great your stopping problems before they may occur!
