Once you have made everything just how you like it, occasionally you might want to make sure things don't move around, or at least, return when you want them. Here are a few tips.
1. To make an item's home somewhere, type @link <item>=<newhome>
2. To stop people taking items, you can either lock them so they arent permitted to take them, or at least make it so if they drop them they return them.
3. If an item of yours has gone astray, or often is taken by other people (and you dont mind but often want to get it back). Create an action on yourself which will return the item to you. Once you have done, on typing get <item> you will find in your hands the item, just like magic.
