I propose to split the topic and discuss the creation
of ACL for MW in
this thread.
I see three sub-tasks here:
0) Writing a good proposal of how ACL should work. Will it be based on
namespaces? or maybe categories (although it's hard to imagine)? or
maybe per-page access? I can help to describe this vision document.
Yury, why is it hard to imagine per-category access? :-)
