Extension:SpecialTalk

This extension adds a talk tab to special pages. These talk tabs link into the project: namespace. The target talk pages have the same name as the originating special pages. Unlike "usual" talk pages, unless someone puts a backlink to the special page in a talk page, you woudn't have one, since these talk pages reside in the Project: namespace, and only link to their respective Project: pages.
