Hi David,
Sorry for the delay in replying.
In Family Safety, your children can send you email requests for new apps, games, or websites they want permission to use. You can always deal with those requests individually, but you can also manage them all in one place on the Family Safety website.
You may refer to the sections “Set limits on the websites your child can visit” and “Set restrictions on games and apps” from this article to check if this helps.
Set limits for when and how your child uses the PC: http://windows.microsoft.com/en-us/windows-8/set-pc-limits
Keep us informed to help you further.
