What’s the difference between a shared drawing and a published link

A shared drawing is accessible to a group of people, based on personal invitations sent to them by the drawing owner. A published drawing is a drawing that the owner has made available to the public. Publishing a drawing generates a unique link to it that can be opened by anyone. The link can the be distributed via e-mail, IM, blogs, social networks and more.
