Well, the author of vBookie added support for my hack a long time ago when it was still eBux / eStore, but due to legal issues, I had to change the name. So when he added support for vBookie, he did so for eBux / eStore, I'd really hate to ask him to update it again and add another option for vbBux / vbPlaza, so I just created the vbookie_integration folder as a way to not bug the maker of vBookie. However, now that its been a bit more stable and eBux / eStore is no more, I might send him a PM on this subject again.
ALSO NOTE: For branding free customers of vbBux / vbPlaza, the v1.5.7 Beta 1 is for download at
