It's not bad and very good!
But there are lots of things missing in the plugin and it would be better without using ProtocolLib. Uhm and why is the ProtocolLib source in your plugin?
Why would it be better if it wasn't using ProtocolLib? It is much easier for me and other Developers to use ProtocolLib because it makes it less code then it needs to be.
And because i exported it into the file, don't know why.. was just feeling like it.
Version: 1.0
A plugin that is definitely recommended. You can
prevent people from doing unpleasant things on your server.
