Take a look in the skin folder and search for the element in which "Rafis" is written. Edit this element through a program you have and put the new one back to the folder.
If you can't do that, upload and leave the element here, maybe someone would do it for you.
lmao, it's the scorebar-bg the name (in this case Rafis) is written on the scorebar. Currently, it is not magically interchangable per person playing, you have to change it manually maybe in lazer lol
