Enable viewers to add tags
''I wish family to be able to add tag information as I will be uploading MANY photos from over the decades and i want everyone to contribute to the tag information (as well as download and print). It would be nice to be able to prevent people from deleting photos but otherwise have free access to them. Can they do this tag updating if I share a "gallery link" or do I have to give them full access for this? Most likely I will be buying more space but I'm seeing how this service goes. Thanks.''
