We are using Public Shares and we want to make it clear for internal users that upload documents to Public Shares that they are only allowed to upload unclassified documents. So we would like to have a banner in red on any Public Share page that says "Please do not upload any classified documents to this Share". On the Authenticated Shares page, we should not have that banner. Can this be done by using the custom Java Script option? And if so, what should the script look like? Many thanks.
