In our location Comment and Markup is common, however we would like to prevent secondary users from making changes to initial comments.
We do not want to set security settings preventing additional comments, and we do not want to flatten the document to embed the initial comments. We have tested the "Lock" comments feature, and found that any other user can unlock the comment and make changes. To us this ability seems to compromise the validity of the original comments.
Does anyone know how we can secure / lock down one user’s comments, while allowing others to continue contributing to the Comment and Markup process?
