I stay on the default mainly because 1) I'm plain and boring and 2) it seems to load the fastest for me (and i'm on a 22K connection so I keep things as quick loading as possible) - course, it's probably all just cache or my own perception really.. 3) I'm too lazy to fiddle with the others :-D
Glad you guys like the variety. Unfortunately the styles will die (temporarily) when we upgrade to the final version of VBulletin 3.0. That said, the final version of VBulletin has much more controllable stylesets.
That said, they still might not be used depending on how the VBulletin/PostNuke combination is worked out (may have to do all styles from PostNuke).
Yes, they will come back better than before and rather quickly. It's just that Vbulletin 3.0.0 RC3's stylesets aren't compatible with Vbulletin Beta 3.0.0. As a result, they have to be recoded by hand.
