Photopost will not be compatible with vbulletin 4.0 till we can even look at it. They are in the early alpha stages based on there notes on there site. We are on the beta list of developers to obtain copies so we will not know anything till then. We should support
vb 4.0 when it goes gold which should not be for quite some time.
I think what they are doing now is preselling licenses. I dont see how they can jump from an early alpha to a gold release by months end.
