Simple experimental collaborative environment
Using simple Javascript/Html tools, you can create very easily your own collaborative environment. (If you don't have your own webpage, you can get one at Weebly).
Chat
For the chat, use Mozilla's TowTruck; You simply need to include<script src="https://togetherjs.com/togetherjs-min.js"></script>in your <head> section, and then in the <body>
<button onclick="TogetherJS(this); return false;">Start/Stop Chat</button>
Just send the link to the other members of the group.
Board
Next thing you need is a common pin board. Get a free account at Lino it.Next create a canevas (say "Collaborate"). Finally, insert the reference to your canvas in your page:
<div> <iframe src="http://linoit.com/users/XYourNameX/canvases/Collaborate?inner=1" scrolling="no" frameBorder="0" style="width:640px;height:480px;border:1px solid black;"> </iframe></div>
That's it. you have your page with chat and common pinboard.
