Suggestions:
-Add
translations support.
-You have this code in spanish and you should translate it to english.
PHP Code:
gSoundFKReport = CreateConVar("freekill_sound_allow", "nano/beep2.mp3", "Reproducir sonido cuando un TT escribe el comando");
-You could add a cvar to control if the msg is visible only for admins or for everybody instead of make two differents codes.
