Privacy and Admin Privileges Questions

Hello,

I'm with a nonprofit called Worldreader and we have noticed that pads set to the "all workspace members can access" privacy setting are still viewable by anyone with access to the URL. While the "invitees only" setting removes this issue, it then requires everyone to be invited to each pad to view it, which is not ideal for a number of reasons (ex: large number of invitations, adding new users, etc.) Is it possible to have a sort of mid-level privacy setting that allows pads and their URL to be exclusively viewable to Worldreader users without being invited?

In addition, we have a large number of pads that have the "public" setting and it seems that only the creator/owner of the pad is able to change the setting. Thus, is there a way to bestow administrative privileges on a user so that they can correct this issue instead of having each individual user change the settings of the pads they own?

Thank you for your help in clarifying these issues.
