The scoreboard is shown once upon successfully joining a server. Accessing the scoreboard in game can be achieved by pressing the TAB key.
 Anatomy of a scoreboard:
- The current score of the game
- This number is the ID of the player on the server. Use this number to kick people from the server using Votekick or Admin's Rights.
- This is the name of the player.
- This number represents the amount of kills the player has.
