I've figured out a feature! Yes...
User...rank...title things.... We'll call them user titles!
See the little tag under my username? Where it says "Twilit Kitsune"? That's where yours will be located. Now, I'm not sure if there's an maximum or minimum of letters. However, for sake of convenience for now just assume the length of my own is the limit.
I've yet to figure out how to make them a user-accessible feature, so you'll have to tell us what you want! Just PM Mew-chan or myself what you want your user title to say, and we'll fix it right up. (Please keep it polite though~)
