Can you make discussion moderators being able to add categories? That's what they belong to do, not only admins.
I don't know whether they can or cannot, but if you tested and this feature does not exist, you could always contact FANDOM

When will my request be answered? The time is what annoys me... making me nearly lose patience.
FANDOM deals thousands of these requests everyday, you need to be patient
Okay.

I seem needy :P
