Follow people without typing in their usernames
Snapcodes! Use them! Hopefully you know how to do this by now, but if not... Snapcodes are like little ID badges, and every user has their own unique one. When you see one, open the Snapchat app, position the code on screen, and hold your finger down. Boom -- now you follow that person. And if you have no earthly idea who to follow, here are some of our favorite Snappers.
Change your privacy settings to control who sees what
Snapchat has an unsavory reputation thanks to its humble beginnings as a dick-pic superhighway, but it's come a long way. Manage your privacy in the Settings menu, where you have the option to restrict who messages you and who views your Story. You can also block people from the Settings menu, in case things are getting out of hand.
