Ok, I've got a working demo in place. It's a little clunky, but I've got it working enough that you can see it in action.
Step One - go to
http://www.npug.org/forum
Step Two - log in with "tashby" as the username and "npug" as the p***word
Step Three - after you've logged in, go to this URL:
http://www.npug.org/forum/chat.php
In a few minutes, you'll be logged into the #npug channel on OpenProjects.
A few things to keep in mind. It's a java app, so you'll be promted with a box to approve the install of the java applet. Also, this really only works with Windows machines.
