How to Make Someone an Admin on a Server on "Garry's Mod"

Garry's Mod is a modification made for the Half Life 2 game (and related games) that lets you manipulate in-game objects and create pictures and videos. If you are running a Garry's Mod server you can issue a command through the in-game console that will let you make another player in the mod into an admin which gives them more powers over what they can do in the server.

Start Garry's Mod, select the server you want to join from the master server list on the screen and double-click on it to enter the server.

Open the administrative console by pressing the tilde key (~).

Type "sv_add_admin /username" into the console where "username" is the username of the player who you want to be an admin.

Press "Enter," then type in your server administrator password and press "Enter" again to make the user an admin.
