Hi! What is your username?
This guys minecraft name is:
PortataBg_YT
U can also search older names of people on
Namemc.com
U will track people easily with it.
If there are multiple people with this name then i would suggest you to ask the person
But now it was kinda useless asking him.
Because if u make an account on cubecraft forums
U need to know that u need to use ur Minecraft Name
Don`t feel unmotivated. But its just a tip.
