Oh really? That's not very encouraging...hmm...
I'm going to try and do as much as possible with vbulletin hacks now, rather than trying to integrate 3rd party products. Better to keep it in the family and you know its all vb code and it all works together.
I came across this thread the other day. Its a simple way of creating a vb gallery, and I'm going to try and see if I can use it as a simple classifieds system.
