This is a simple snippet for two commands, beep and nobeep. Beep is used to send an audible noise to a person who doesn't have nobeep turned on. Nobeep is used to block incoming beeps. I have nobeep set as a command that can only be used by people with 12 or more status but the snippet doesn't include that restriction.
Easy to install and very helpful for those times when you're in a different window and someone wants your attention.
