“This plugin is simple enough. A Moderator sets up an AFK spawn point, and when people type in /afk they are teleported to that point. You can choose whether or not the players will be able move once they go AFK and many other things in the config file. The only permission this uses is for the /setafkspawn and you must have the permission node “afk.setafkspawn”. The commands are below. The plugin is pretty self explanatory.”
Seriously this looks great for people who need to keep going on afk. I can see its more pvp centered but it can have other applications such as stopping AFK machines for good!
