[Joaquim Pereira]

He is actually able to pronounce that surname but he does it horrible. I know it because the first time I heard him pronuncing 'Pereira' I thought that the program had bugged  

In any case if you change your name ingame it will only affect the way CreeChief pronounce your name for us, you can configure the program to call you whatever you want.

I don't want you to suffer more than necessary.  So, I tried... 
Thanks, both of you.
