Well, matching my Youtube name, as well as wherever else I might use the name ZillionBrain (because just Zil is often taken) is one reason. Also, for a somewhat complex reason, a friend of mine might be offended if he ever saw that I used the name princessmilk. (actually this is kind of the main reason I wanted to change it) Anyway, If my reason isn't good enough, I guess it's just not good enough. My only other argument would be that I have not been here very long, so I doubt most people would be confused by my nickname changing, if they even noticed in the first place.
