Very nice plugin! That's exactly what I was looking for, I've seen this concept in a Minecraft Server and I finally found this plugin. It works very well.
Hello, the plugin works perfectly. The reason for that is that you have executed the command with the wrong arguments: in the "respawndelay" parameter you have to specify a number and not a string. Anyway I've just released a new version of the plugin. Since it's not my mistake I ask you if you can please change the extremely negative review you left, thank you.
