Our partnership with Poptropica Wiki is long outdated. The partnerships tab on the navibar doesn't create any "theological" endorsement. The patterning program is primairly obsolete and it generates traffic that doesn't really take anytime. Our partners are not very well related content wise but the partnership are more or less linking.
I took up the idea a-while back as it used to be something that was reccomended by Wikia Staff a lot to do for promotion. Several wikis do it, and we have asked been asked by multiple wikis to do a link exchange with them, or do so with other religion related wikis (Religion Wiki and Judaism we would likely not link with any Pagan religions).
As I said, it doesn't take a lot of space to do so, and so we probably wouldn't remove of it unless we decided to use that space on the navbar (might as well use it). Its just promotion for the sake of SEO and cross-wiki(a) promotion.
