This isn’t directly directed to Panda, per se, however, I do think it might be useful for the Panda community.
There’s this program called “Gabbly”, that was programmed using AJAX. Basically, it’s a chat program that allows you to have a chat while viewing a webpage. All you need to do is put gabbly.com before the URL.
This would allow the Panda 3D community to chat, while browsing the forums, etc. It runs in the browser, and is compatable with Safari, Firefox, and IE.
The one downside is that there are no moderation capabilties, and you can send an unlimited number of messages per second, making it pretty easy to spam it.
I found this on a filmmaking forum I visit, and I thought it might be useful.
