Not Tono, but it's simple: if we start making categories for everything related to an article, you'll never stop. Catergories exist to make navigation between related articles easier, not to make links to anything remotely connected to it. That's why we have the policy of putting new categories through a War Room discussion before we acually implement it here. Also, a lot of the time, categories can be a little ambiguous. Easy example: we don't have a category for villains or antagonists, because so many characters are both good guys and bad guys at the same time. It wouldn't really add much to being an easy way to navigate the wiki. Same goes for airbending and spirituality. We don't even really know how the heredity of bending works, is it spiritual, is it genetic, is it both, who knows. Adding it is not much of a benefit here.
Hi Tono! I'm Quamboq from the German Wiki, and I recently gained the Admin-status of the Nicholas Flamel Wikia. I wanted to adapt the Familytree-Template (in German Stammbaum-Vorlage) to this Wiki and copied the full Code of the German Wiki. Just like I had imagined, it didn't work. But what can be the problem?
I saw your edit to your userspace and I thought I'd just pop on in and wish you a really happy birthday ! I hope you have fun, 18 is a good year, and I hope you had a great celebration (or are going to, timezones haha)
