In a school WP site there used to be a main category "Blog" with n subcategories for each class:
Blog |__ Year 1 |__ Year 2 . . |__ Year 9
Now we want to introduce the "Announcement" category, however this category will have the same subcategories as "Blog"
Announcement |__ Year 1 |__ Year 2 . . |__ Year 9
No big troubles since WP will create different slugs for each subcategory, however I feel like wasting subcategories and making subcategory selection a bit confusing.
I wonder if it makes sense promoting the "Year x" subcategories to main category and couple the other main categories to properly address categorising.
For instance, a post with main categories "blog" & "Year 2" will be related to class year 2 in the blog, while a post with main categories "announcement" & "Year 5" will refer to an announcement for class Year 5.
What do you think?
