If you consider that they were not running any custom styles then it's not a good advert for vB4 IMHO. One is left wondering just how difficult it is going to be for our own boards, esp. with custom styles and modifications.
Hmm, having the site down for so long is very unprofessional, I have no idea what's going at vBulletin, developers leaving at the same time, new management, new posting rules, new prices, og well, I just hope the new version is good.
Is very profesional upgrade a site without test and fix that upgrade under duplicated environment.
Since vb4 announcement seems they "do" before "think", just in reverse order that they should do.
Licenses, prices, features, update own site... what will be next?
