paulus1031 a zt2 instance requires the user to pin to their board, so the website doesn't require an account of its own - though the website owner should have the requisite permissions for sharing artwork. (my client is an interior design firm and I noted they need to get authorization to share images from their contract photographers - and at what size.)
the social area button in the banner is different kettle of fish entirely. that would be a link to the website owner's pinterest board, not a bad thing for JB to have for sharing templates and screenshots, etc. That should be a different icon, with its own class - and I'm not sure this latter thing is happening; they appear to share the same class. social area pinterest <> zentools2 pinterest.
