So I figured this post is more appropriate here than in the Wiki Design Forum, as is it for a UCP Wiki.

I would like to switch my design to use namespaces. It is about a game, which has two modes, Story and Online. So, I want to use is the namespace Story: and Online:

The idea is that I want to keep content on articles in the namespaces separate, where similar things may be cross-linked by a link at the top of the page to points to the other, content on the article page would be confined to either content about Story, or content about Online. That way, a reader that comes to the Wiki will be confined to content of their game mode of interest, and has to change namespace through a link clearly labeled for the other mode.

There may be content common to both, such as an article page for a game update, which I reckon belongs in the common namespace.

Also, it may be possible that a DLC is later released for the game, so I would use a new namespace for that.

So what I am asking: what kind of considerations would I need to think about before making this change?  
 * Could a user, by default, be confined to searches within a namespace and the common namespace, and explicitly indicate a need to search the other name space?
 * Would there be a way to modify the wiki activity log that shows up on the right side of the screen such that it is confined to the namespace of the page that the reader is viewing, or possibly both the common (excluding the other) and the viewed namespace?
 * How do Categories relate to Namespaces? Can a category be confined to a specified namespace, and that category be separate than the same category with the same name in the other namespace?
