Cooldown message

This is a message that could show up as a cooldown message. A cooldown message is a message that is being send if a player presses something very often (if you didn't know yet). THIS DOES NOT RANDOMLY SHOW UP! YOU WILL HAVE TO MAKE A SYSTEM THAT SHOWS THIS. If you want to send this message, change the '@a' to something like '@p' or a player name! Have a nice day :)
