Interesting Uk. Why the "thank god" your not worried kevj comment? Are people not allowed to be concern of the future of vbulletin? And secondly, who's scare mongering? And what rumours are you speaking of?
Last time I checked, Developers left (fact). many people are concerned over at vb.com (they just don't bother posting it here) fact.
Like I stated and I'll say again. I'm not concerned but if 4.0 is anything like 3.7/3.8 you'll be most certainly eating your words.

I'll probably even be here telling you I told you so as well.
Let's hope it's not the case and then instead of thanking god we can pay homage to the developers.
