When you have created a claim you will have several different options for customization.
See those messages you get when you enter and leave residences? Those can be customized using:
/res message residencename enter messagehereand
/res message residencename leave messagehere.
You can further divide your claim into subzones, in which you can have different settings to your main claim:
/res subzone subzonename.
Additionally you can rename residences using:
/res rename oldname newnameIf you are renaming a subzone, oldname must be the full name(parent.subzone), while newname is only the new name.
