Template documentationA helper template for {{Sockpuppet}}.
If the sockpuppet category page does not exist, it displays a garish warning box
There is a link to create the category page, preloaded with the contents of {{Sockpuppet/categorise/preload}}.
Yes, it's ugly, but it works. And it should help to avoid Special:WantedCategories filling up with sockpuppet categories
