From viewing the actions of photopost over the last year, it is easy to assume they would like to phase out vbgallery and convert those users to photopost gallery. Otherwise, as mentioned above, you would see vbgallery available for purchase alongside their other products. There would be more support and newer features. VbGallery is not even listed as a product on the home page.
The lack of visibility of vbgallery is somewhat understandable. Photopost is a successful piece of software with many clients. Creating confusion by adding vbgallery to their order or home pages is not something the company wanted to do.
I am sure the idea is not new to the Photopost staff, but I will recommend it anyways. I think the best way to preserve vbgallery and help it grow would be to create a separate website for it. This would remove the unwanted confusion on the photopost website and help resurrect the vbgallery community. It is my opinion that vbgallery will eventually die out if something is not changed.
