title: Implementing a chat application in Ruby on Rails
body: <p>Basically, the app has to support sign up/sign in functionality and allow user to add friends and allow friends to chat.Since, I am just starting? with rails it's a bit overwhelming. How should I go about it</p>
  
  <p>Also, the aim is not an application for production. 
  It'll be great if you could link to some working demos of the same.</p>
  
  <p>Thanks!</p>
