If you have children ages 6 to 20 you need to be aware of these apps: *Vault apps which children as young as 8 years old are using to store and hide pornography *Yik Yak which is the equivalent of a digital bathroom wall where users can type anything at all, and anyone within a 5 mile radius can read all local comments *Kik which is meant to be a "safe" closed texting environment but has become a favorite method among online sexual predators. **For more info on Yik Yak read: "The Barrel Has No Bottom : Yik Yak Review: Another Anonymous Social Media Site Perfect for Cyberbullying & It’s Worse Than Ask.fm" bit.ly/1h8KInV
