I coded a staff list plugin for my server and decided to share it here in case any one else might find it helpful.

Features

Allows players to view the staff members of your server and whether or not they are online.

Commands

/staff : Lists your server's staff members and displays whether or not they are online

Permissions

staff.* : Allows full access to the plugin once it gains more features, but has no purpose at this time. staff.list : Allows the use of the /staff command

Installation

Put the .jar file in your server's plugins folder
Restart or reload your server
Edit the default config.yml with your server's staff members and server name
Restart or reload your server again

Configuration

Make sure to follow the format of the default config.yml. You must use spaces and not tabs.

Default config.yml :

#Follow the format of this default config file
#The staff member must be the same item on both the "Staff" and "Rank" lists in order for the plugin to work properly
Server Name: NyxCraft
#Make sure to use 2 spaces instead of tab before the '-'
Staff: 
  - Gunner_Skale
# -StaffMember2
Rank:
  - Owner
# -StaffMember2Rank

To-Do

Add the ability to add staff members in game
Add a config reload command
Possibly an option to change the plugin's chat colors to correspond with your server's theme
Comment any other suggestions you have

This is the result of /staff with the default configuration:
