This is a page about style for pages and articles on the Meta-wiki.
The Meta: namespace is generally reserved for articles about Meta policies, style, and coordination. Discussions that touch on all Wikimedia projects, or on coordination across languages, are appropriate for the main namespace.
Subpages are used where all subpages are subsets or variants on a parent page. There is no consensus yet about where else subpages should be used. As of March 2009 a discussion on Babel about how to name the pages for "updates from <language> Wikipedia" is ongoing.
