Patch 5.0.4 Cool Stuff #7 - Login screen sound
The sound from the login screen has always bugged me. It's so loud, it startles me, and it totally stuffs up when I'm trying to "stealthily" log into WoW. I used to just mute my computer for the login so nobody would know I was logging into WoW.
But since patch, there's this little sound thing in the top corner where you can mute that "DOONK" sound! Yay!
Now I can sneak into WoW. Awesome!
