Please add plugin Command CoolDown Site: https://dev.bukkit.org/projects/command-cooldown
Command Cooldown allows you to set a cooldown for any command, set in a config. What can you use it for? Standard users might have to wait xxx amount of seconds between uses of a command like warp, while donator ranks would get lower, or perhaps even no cooldown between uses. Or perhaps you just want a 60 seconds delay between uses of /smite! It's all possible!
