Head over to the following page to access the chat: http://www.kirupa.com/me/irc.htm The previous URL also has the link to a java-based chat that connects to the same IRC server.
The link again is: http://www.kirupa.com/me/irc.htm
Also, if the chat room seems to be empty, remember, most of us live on different time zones. I have found that the most of us hang out at any given time in the evenings around 8 PM - 12 AM Eastern Standard Time.
Hope to see you all there!
