I've recently set up the newest MediaWiki install. I'm trying to force users to make an article part of a certain category. I'm using the SelectCategory extension to ask them when editing an article, however it is possible that they don't select any categories and simply save the page without it being attached to a category.
Is there a way (extension/setting/hack) that I can make a default category that all new articles will be a part of if they aren't added in another one?
