Haha yeah.
There is a beta out that you mess around with, but the source code has not been released yet. They just wanted to allow people to find bugs before they do their first beta release.
http://beta.vbulletin.com/vb3/
They don't have the actual new vb3 style up, to keep it a surprise, but the new functionality is there.
Anyway... I hope to see a beta within a few weeks. And yes, I will not be changing these forums over until I can put a few of our ChiefDelphi-specific features into it. I'd also have a few people from here go to that beta forum and go crazy on it for a while, to find bugs and other things. Once we think its ready, I'd switch over to vb3. It most likely will not be any time from Jan->April. So hopefully a stable version comes out soon, eh?
