If you have a person in the chat that won't be quiet but you don't want to kick them. Then with this script if you have HalfOp or higher go "/mute " and it will place a silent ban on the person for 20 minutes.

If you would like to change the standard time under the 2nd to last line change the 1200 to how many seconds that you want the person to be silenced, remember it is SECONDS not MINUTES.
