I think our host (
Pair ) is anti-vB.
We get PHP and mySQL support.
but we can only use 5 x 20Mb Databases. And you can't store HTML or binary files in them. So that pretty much screws vB over at the first hurdle.
As for my preference.
UBB is more professional looking, whilst vB could be aimed at the personal market.
Also i've seen vB throw up a lot more errors than UBB in my time, usually something to do with the DB. UBB IMO is more reliable. BTW I still like vB, just not as much.
