When our wiki was updated to version 2.1 it provided a mechanism for adding labels to pages.
When editing a page, at the bottom you'll find a "Labels" section. Since the wiki contains pages which are still under development, pages used for discussion of new features or technologies, pages which are essentially outlines in need of content, and "mature" pages which are essentially final versions, the use of labels on our wiki could be quite useful.
I am proposing the following labels be used whenever appropriate:
under-development - The page is currently being developed
discussion - The page is for the discussion of a new feature or technology.
needs-content - The page needs volunteers to contribute content.
obsolete - The page contains obsolete information and exists for archival purposes only.
