Plugin for Page Categories

Hey everyone,

First post here at WordPress.org, and I’ve been toying around and have a huge question.

I’m using a multisite WordPress with subdomain wildcard. I’m not using it for a blog, but rather more of a CMS with organized pages. I want to assign Pages to Categories in regard to language. I have subdomain wildcard to represent the region (which I have down perfect) (ex. eu.domain.com, au.domain.com, but when it comes to the languages, I also want to use or have it appear as if the page is in the language “directory” (ex. au.domain.com/DE/, eu.domain.com/ES/).

I noticed that I need a plugin for this type of operation. They are not blog posts, just pages. What is the LEAST buggy as far as little conflicts and hopefully easy to use.

Any thoughts? Thanks ahead of time!
