Accessing Wiki Permissions Bug
Accessing Wiki Permissions Bug when Wiki in Area with no Public Access
I've discovered that a Registered User can access the wiki when all the articles/namespaces are contained within a category that is out of normal access for that usergroup, i.e. an Administrative Area.
Access includes not only being able to post a new article, but also getting access to the lists of changes and existing articles.
This needs to follow the basic forum permissions where the namespace is located in display view.
