Hmm, I wonder what would have more luck in the long run; a million monkeys at typewriters or a million Internet Brands staff. All desperately trying to come up with a stable vBulletin 5.
That ranks pretty much up there with the MySQL credentials being found in faq.php found in earlier versions of vBulletin 4.
There won't be a vBulletin 6. vBulletin 5 is a complete failure, and I'd like to see one person argue against that and provide statistical information that it isn't a fail. Look at vB.org for example, a year+ in to this debacle, there aren't even 50 modifications released. The mod with the most installs is at 77, and most don't even have 300 downloads. vBulletin has a huge market share lead still, however with IB running the show that will dwindle down in the coming years as 3.X vBulletin's are still the most widely popular version will eventually break with server updates that are inevitable.
So I just logged on to vb.com itself to read the official discussion thread and I saw that we should be able to upgrade a vbulletin 4 site with a loaded cms, into vbulletin 5. I missed that part of the announcement, I'd sure like to see a site that's successfully updated from vb4 w/cms data to vb 5.
The best way to keep vBulletin relevant is to keep talking about it, good or bad. I am super excited to load up vB5.
