Seeking Advice on Restricting Access to a posts to those who have the permalink.

Hi MattV, indeed that was meant to say " do not want" - I corrected the typo in my OP.

Thanks for the insight. I was under the impression that there was a private node feature that would provide such functionality.

I will explore removing the component that lists all the messages.
As far as I can tell these are the All Form Topics button as well as the Next Topic and Previous Topic buttons.

I believe the only other way users can discover all posts is by inspecting the Admin users profile history. Do you know if I can block access to some admins profile history?
