Hi there!

I love Zenphoto. The only thing it can't do that I'd like it to, is integrate membership with my existing vBulletin system. Is there a bridge or hack somewhere out there (or does anyone have any idea how to do so) that will integrate zenphoto into my existing vBulletin system so that my members don't have to register or sign up for multiple accounts?

Thanks!

No, not that we know of. There was something similar for Wordpress I think. Maybe you can adapt that but that would be surely some work to do. Generally all known extra stuff is to be found here: http://www.zenphoto.org/category/Extensions/

Your best bet may be to ask on vBulletin.org... I've seen a couple threads about Zenphoto there but I know what if anything ever came of those discussions.
