We’ve changed the way we auto-name projects so that you can save more than one similar project. This enables you to save multiple versions or, when making cards, to save the save version with different text to different people.
NOTE: the dotphoto cart does not allow duplicates, but photos that are different by even one pixel are considered unique. With cards, the cart considers the first image. To place more than one of the same product in the cart, you can use a different photo or slightly crop and save-as-new the same photo.
