How can I get the number of missing links that are in my Wiki? We have a lot of articles about all kinds of things that haven't been written or stubbed yet, but we want to provide a progress bar so the community can see how close we are to being more complete.
You can see the wiki here: http://worldeditor.org
If you have any tips related to that wiki, please do share.
You could check the source code that generates this page: http://worldeditor.org/Special:WantedPages
And then change the select query to inlcude a count() statement.
Dunno if this is the information you're looking for, but:
At the left side of your MediaWiki page, under Toolbox you have Special pages; and on that page, a link to Wanted. That's a list of nonexistent pages pointed to in the Wiki.
