Hey Jordan,
Thanks for your question! When adding the Private flag to a category (or wiki page), that page becomes visible only to privileged users when browsing or searching the site. Standard users will only be able to access that page if they have the URL for it.[br]
Dozuki does not currently have specific functionality to restrict category access to certain teams or users, but this is a common request from our customers. I will submit a feature request to our Product team on your behalf.
