Mediawiki provides a special page to view all "Wanted Pages" (pages that are linked to but that don't have existing articles yet) by visiting /Special:WantedPages on the wiki. Check out Wikipedia's Wanted pages to see what I'm talking about.
My issue is that the Wanted Pages list will quickly fill up with pages to special namespaces. At the moment my wiki is chock full of wanted pages in the Template, Talk, and Category namespaces, to name a few.
With so many links to special namespace pages, the articles in the Main namespace (the ones my users actually care about) are getting lost. Is there any way (through an extension or what have you) to create a list of wanted pages that are only in the Main namespace?
