There are few settings related to sharing of ship profiles and a ship profile review that can be changed.
Allow users to forward a share?
Users that have been given shared access to a ship profile from your company can be allowed to share that profile with people outside of their company.
If users are allowed to forward a share outside of their company, you can add restriction to make that share subjected to approval from the original sharer of that ship profile. If restrictions are applied, the original sharer receives an email when their shares are forwarded outside of the receiver's company and need to give their acceptance (or rejection) before the profile becomes shared.
Allow reviewers to comment on fields?
This option is a part of a review process and does not apply to normal sharing of ship profiles.
Reviewers of a ship profile can be given the option to add comments per field in the review process. Owner of ship profile will also have to option to reply to those comments. Note that comments will not be mentioned or displayed on print version of ship profiles and no notifications are given when comments are added.
Send email to fixed emails when ship profiles are confirmed
Administrator can give a list of fixed email addresses that will receive a copy of an email notification when a ship profile review is confirmed by reviewer.
