Extension:CatTalk

The CatTalk extension enables talk pages to categorise their corresponding pages.

Usage
On the talk page of an article, use the parser function, replacing your category with the relevant category. Once the talk page is published, the page the talk page belongs to should be a member of that category.

The function should work in all namespaces, and works with templates - so you can put it in a template, then transclude that template onto a talk page, and the talk page's corresponding page will become a member of the category specified in the template. This is particularly useful for WikiProjects doing categorisation, as well as for monitoring recent changes based on a tag left on the talk page.
