I have a "copy" of Invision laying around, unfrotunatly it's no longer a recent version. I'm moving over the phpBB int he name of integration with other scripts, as you'll find alot of free scripts can integrate with phpBB usertables. And some have invision/vb too. I'm anxiously awaiting phpBB3 though as it's meant to be shitloads better thant he current phpBB2 which is so basic it's untrue compared to other packages.
