Plugins

Since Nullcraft attempts to be as true to the original game as possible, there are only a few plugins installed.

LWC
LWC is the chest-locking plugin used on the server, allowing players to keep peace in mind knowing that their items won't be stolen by others.

Chests are automatically locked when you place one down, as the message in chat tells you.

All commands for LWC can be seen in-game via command: /lwc Most actions are performed to the target chest by punching it after executing the appropriate command.

Public
Public chests can have items put in and taken out of them by any player, but can't be modified by any unauthorized players.

Donation
Donation chests can have items placed into them, but can't have items removed by any unauthorized players.

Private
Private chests are only usable by authorized players.

Password
These are the same as Private chests, except players authorize themselves until they logoff by entering a password. This allows players to share access with others without explicitly adding them.

Info
Information about a chest can be seen, including if it's protected, by who, and what type of protection it has by using this command: /cinfo

Adding and Removing authorized players
Players can add or remove other players using the below command: /cmodify Adding usernames after the command will add them to the chest, while prefixing usernames with a minus sign will remove them from the chest.

Players can be given authorization to use the /cmodify command by prefixing their username with the @ symbol.

Persistant mode allows you to use the same command on a number of chests without having to retype the command after each execution. This can be used to add a player to a group of chests for example. /lwc mode persist 

There is much more information on the official wiki of LWC.

Sleep Percentage
This allows players to pass the night without having to have all other players online sleeping.

It is currently set to only require 10% of the current online players to be sleeping to pass the night.
