Here's my take on a premium slots plugin!

Explanation:

Say you have a server with 10 slots but in this plugin's config you set 2 slots to be premium slots. This makes it so 8 players can join the server freely, but the last 2 slots can only be filled by players who have the bypass permission node for this plugin (permission is "ps.bypass").

Recommended use:

Default user group does not have bypass permission but all, or a certain level of, premium ranks for server do have the permission node.

Dependencies:

This plugin relies on Vault for permissions! Download Vault and add it to your server's plugins from here: https://dev.bukkit.org/projects/vault

Commands:

/ps

/ps toggle

/ps reload

/ps version

/ps slots <slots>

/ps msg <message>

Permissions:

ps.bypass - Not default - Allows a player to join a server when the server is in Premium Slots mode

ps.admin - Not default - Allows a player to use all PremiumSlots commands

Open-Source:

This plugin is open-source, and you can find the source on: https://github.com/ZeezCode/PremiumSlots
