I have made a server and am introducing mini-games. I want to make it so they can join an arena or game by clicking a sign. Is there a plugin to help do this? Or any tutorials I believe you can use Essentials maybe? Not sure. Any help is welcomed thanks!
Yes, there is: http://dev.bukkit.org/bukkit-plugins/command-signs/ If you want to add command, type: "/cmds 1 /command" and click at the sign For remove, type: "/cmds remove" and click at the sign.
