Adding Admins
As the owner you probably want to give yourself full admin privileges on the server.
Open up SteamID.io to find your SteamID.
Open the
admins_simple.ini
file found in\csgo\addons\sourcemod\configs\
.Place your
SteamID
along with quotation marks on both sides of it, add second additional quotations after it and set your preferredAdmin Flags
in it.
Example:
txt
"STEAM_1:1:12121121" "z"
See more about the flags here.
Save the file.
