Snapchat for Web, This a new cool thing by Snapchat. I sometimes use Snapchat to communicate with people from the site, especially in the old days. Anyways this is basically a way to communicate with your snap friends on the web. One thing when you first login, you will need to be logon in your snapchat app, because in the web browser snapchat will asked via your snapchat if is you trying to login. i like it is a cool feature.
