Please stop adding categories that are irrelevant or not created by the admins. I've been seeing categories based on ethnicity, categories that are simply alternative wordings to already existing categories (e.g. a category called "Youtaite female" has been made, even though "Female Youtaites" already exists..).. it's annoying and unnecessary.
If there is a category Youtaite Wiki does not have that you feel is necessary and relevant and needed, please contact one of the Admins and bring it up to us. We will consider using it and listing it on the navigation page. Otherwise, making extra categories is not needed and may cause confusion to guests among the wiki.
