General Overview:

![overview](help_mtg_version.png)

### Item to be generated

Place item to be generated (only 1 is needed in this slot) in Item to be generated slot.

### Item in progress

Observe the progress of the item replication at Item in progress.

### Member access control (MAC)

Add a playername 1 per line (That's it, just 1 per line, no comma or anything else) then hit Save.

To quickly lock, unlock or open to public click the Only U button (This button will change who has access, Only U, Members, Public)

> You need to save when you change access level or add/remove a player's name.

What do they mean? (Access Level)

* `Only U`, only you the player who has access to add/remove members, change the item to be generated and change the access level can access the replicator. (Screen shows only if you have access)
* `Members`, only you the player who "owns" the replicator, and those in the Members List can access the replicator. (Members can't change the item being generated or add/remove members or change access level, only take and add to the Collection Pool)
* `Public`, anyone can access the replicator. (only the player who "owns" the replicator can change the item being generated, add/remove members and change access level)

In practice:

I want to make a public apple replicator on my server for everyone to use.

> I'd use the Public access level so anyone can take from or put into the Collection Pool area.

I have a friend who what's to use my wood replicator?

> I'd use the Members access level where I add my friend's playername to the Members List (don't forget to save).

### Collection Pool

This is where the Item to be generated gets replicated to, from here most/all players (based on MAC settings) can pull or put items.

This could be used as a small chest... but really it's for stuff being made.

### Your Inventory

Yup, that be your inventory, the inventory of the current player accessing the replicator. (Nothing special there)

### Upgrading

You can stick it into a furnace with a lot of fuel and wait for it to be upgraded to version 2 (which simply increases the speed at which it can replicate things) and stick a version 2 into a furnace again to upgrade it to version 3 (which simply increases the speed again).

> You can dispose of item replicators by putting them in the fuel slot (bottom slot) of a furnace to be used as fuel, or in the case of upgrading them you put them in the cook slot (top slot) of the furnace to be cooked into their upgraded version. (Currently Version 3 is the highest upgraded version)
