A very basic resource which adds an /invite command to let users invite their friends to whitelisted servers. There's also an /invitesleft command to view the amount of invites a player has left. That's pretty much it.
- just me~
This is very basic, and I'm not here much. As a result of this, I probably won't be updating this much or adding many features.
It uses Java 8, so make sure you're using Java 8 too before complaining about the plugin not working.
In the config.yml, you can set the kick message for non-whitelisted users, as well as the amount of invites per player. Enjoy.
