Have you heard of a smartphone app that allows you to possibly post comments and pictures, even nudes, anonymously? The app is called “SIP.”

At York High School, officials are warning parents of the new app, which is known as "Sip-Campus Pics and Vids," as they believe some students could be using it to post naked pictures of themselves.

You may want to talk to your high school student about this. Don't worry if you didn't know about this as the world of technology is changing more quickly than most change their socks.
