So I made a mistake assuming that renaming a tag would update all references to the tag sitewide and accidentally just created a new tag. The justification is that I decided on "Dark Cure Sky" as there was no official term for the form and "Dark Sky" was already a tag, however at this point it's clear "Dark Sky" is what the form is actually referred to as, and so I attempted to change it not knowing I should've made a BUR request instead. I've been advised to create two BURs and allow people to decide which name they prefer.
