Go to Your profile in Tools menu. There you can change your team initials – these are letters which are shown during the game next to the score and also if you have supporter they are shown in the games on scoreboard. As default settings your team initials are first 3 letters of your team name. If you want to write your own shortcut go and do it, for example my team is called LimeFactory – default was LIM, I didn’t like it so I changed it to LF. So customize BB as much as you can!
