In your opinion is every school a location as well? If that is the case, what about making "Schools" a subcategory of "Locations"? Then schools just need the category "Schools" because they will be locations as well due to the category tree.
Hi Zuri–Yes I think that would be appropriate. I was not aware of subcategories in the wiki. In that case, I suggest subcategories be made also for other pages such as Students and Teachers under Characters, etc. as well.
