Topic on Project:Support desk

Odd question but I'm thinking of one day making my wiki public, for my story's and stuff, but I also use it to take notes and stuff, mainly for said story's. So I was wandering if it's possible to make specific pages only accessible and viewable by me, or specific users, but later make them be able to be viewed by everyone.

I'm fine with extentions. As long as it's not something I have to go into the code and type every single page, which would take far to long and be far to tedious. Do to the sheer amount I plan to add. Preferably a toggle, button or a tag I add to the page.

Mediawiki doesn't have great options for this, but perhaps putting your private pages in specific namespace (you can move after) and using extension:Lockdown

Stupid question, how would I go about doing that, setting up namespaces i mean? To be honest I haven't heard of namespaces until now.

help:Namespaces and manual:Using custom namespaces has some information.
