It's a nice plugin for players to protect their work from griefers..
So basically like towny, but residence plugin allows you to set the size of your land using a stick or any item specified....
first left click the first position
and right click the 2nd position
forming a box whatever inside the area is protected.
What i like about this is you can teleport to that certain area so you can have multiple lands or homes.
you can also set flags (fire,mobs etc), you can also add people in your area just like towny..
