AJAX chatroom

[myron]

Anyone knows where to find a (light-weight) AJAX chatroom sample?

Trying to learn AJAX by writing a personal used chatroom...
Should be better than using Java, since the light-weight nature of AJAX, and we can use 80 port... :)

Please remember to search. You could have easily found this (http://www.google.com/search?hl=en&q=ajax+chatroom&btnG=Google+Search) if you would have just used Google.
