Tutorial

Here is a quick tutorial for ChestList

Once ChestList is installed, place a chest, and place an item in it (ChestList only logs what happens once it's installed)
Type "/cl near"
That will give you a list of chests near to you, the nearest one will be the one at the bottom of the chat, it's ID will be prefixed by a hash.
Type "/cl check", followed by the chest ID (don't type the hash)
You should get a log that looks like this:

You can also check which chests you have used.
Type "/cl list YOUR_NAME" (obviously put your name there)
You should see a list of what chests you most recently accessed.
Now get a "friend" to come along and steal something from your chest
Type "/cl search CHEST_ID FRIENDS_NAME 1" (replace CHEST_ID with the chest ID, FRIENDS_NAME with your friends username)
It will show only the logs involving your friend, this is useful when lots of people have accessed the chest.
If you want to see very basic info on a chest, you can type "/cl info CHEST_ID", this will show you the position and last user of a chest.
To remotely open a chest, you can use "/cl open CHEST_ID"
To see a list of chests near another player, use "/cl near PLAYER_NAME"

You should now know the basics of using ChestList
