I just prefer to call you Gwazi. Cuz just calling you "Magic" feels dumb and I never really grew accustomed to calling you "Magnum" so... yeah.

So yeah, I'll call you Gwazi regardless of which account you use.

But if you switch to the Gwazi account now, then I'll just get confused whenever I need to contact you for the Welcome Back to the Guild RP. :/ 

I mean, you can have people call you "Gwazi" without needing to switch accounts. At this point, there's no reason why you can't just stick with your "Magic Magnum" account and let people call you whatever they want.
