Well as I previously posted vbGallery allows public and private albums same as vbalbums but vbGallery is much more robust. My take on the email is that it is referring to the profile part of vbulletin and turning that off because indeed there is no need anymore since we have created plugins for that.
As far as social networking or other parts of vbulletin that may allow album stuff that indeed I am sure will add functionality with vbGallery in the future thats why customer interaction is needed in beta cycles and the suggestions forum is very important to us. Those are most likely areas of vbulletin the developer has never really looked at as he was probally concentrated on the profile albums feature directly and not other aspects that at first glance would not be easily seen to the user. I myself have owned vbulletin for 8 years and have not looked into the whole social networking aspect or what it includes. I am sure there are many vbulletin users like me here.
Please take a moment to post in the vbgallery suggestions forum as I feel that would be beneficial for the developer to look at in our next beta cycle.
