radical hacks Webcal Occupant Info sent in the following hack...
I have done some modifications to Your Web Chat script.
I added one frame for occupants info. And wrote script UINFO.CGI for reading that info from .whofiles. And that new frame will also be refressed if autorefresh rate is selected, or if not yuo can press the "View Occupants" button.
And if you don't want to use frames (could you explain me why not:-), it looks similar to your CHAT.CGI without frames.
