I came across "this absolutely fantastic _Dark Sun_ wiki":http://www.obsidianportal.com/campaigns/dark-sun-a-trova which I think deserves Campaign of the Month honors. This wiki represents an outstanding example of organization, presentation, and use of the site tools and includes some excellent original artwork.
This wiki is also one of the growing number of campaign in a language other than English on Obsidian Portal; I think it encourages international users to see their work highlighted.
