Create simple auto popup chat system guide or example
Hi
I am developing a game application using HTML5. But I want to emphasize more on social communication with friends and family. Therefore I want to create a simple auto popup chat system integrated with the game. I do not want the chat system to be IN the game, but separated. The game needs to be logged in, how do I go about having the chat system plus authentication and auto popup? Do I need to have it in PHP or JavaScript? Any guide or example that I can refer to?
