Several recent questions from parents about how to allow their kids on YouTube without having them exposed to age-inappropriate comments have persuaded me to show how to set the safety mode on the service.
It’s easy. On the service, scroll to the bottom of the page. Here you’ll see a link that says Safety mode: this will either show that this feature is either on, or off. Click on the link and a popup will appear providing you with a choice.
Voilà. You’re done! Note: This feature isn’t just for young kids, if you don’t want to be exposed to objectionable material, by all means use the feature for yourself.
