Working great on our small SMP server only things I think that could be nice to be implemented is that when a player is in spectator and they use /spec to just unspec the player instead just saying they are already in spectator and the only other thing is the possibility to limit how far players can fly from the point they use the command e.g set to 100 blocks (configurable) before they cant go further to stop players from flying and endlessly generating chunks

But seriously again the plugin works great and awesome work on it so far thank you ^w^
