Smails is a simple communition widget made in HTML/Javascript.

Live demo: http://smails.firejune.io/ (Running with WebSocket, FlashSocket and more, for better real-time results please run it localhost and access with a Websockets-ready browser).

Modules and versions used:
Node.js v0.4.10     http://nodejs.org
socket.IO v0.7.9  $ npm install socket.io

How to run:
$ git clone git://github.com/firejune/smails.git
$ cd smails
$ sudo node app.js

So, access http://localhost:8080 in your modern browser, try to open more
users simultaneously, walk around the page and talk in the chat.

Tested in CentOS 5.6 (Final).

Works best in Webkit browsers, IE 9 and Firefox 4.
