Currently the only way to stop an individual from forwarding a proof to others is to require a login to view. However, we have MANY individuals in our organization that don't have Workfront Proof licenses and need to be able to view proofs and comment on them. Unfortunately sometimes those reviewers decide to forward the proof on to someone else because they think maybe that person should see it. We would like a checkbox added that restricts the ability to forward a proof to anyone else.
