Yes, cuboid is installed and working great.
Pretty much the only command that is available to those who know not much of the all powerful cuboid are/is the "/protect" command.
So, to use this powerful feature and protect your home, apartment, flying turd in the sky, whatever you must use the wooden shovel. The reason for this is that be default it is the tool that you use to interact with the cuboid plugin and make cool stuff happen. The other tool is the sword but it is not necessary so I will not get into that.
So, you have your wooden shovel. What you will do to anti-grief your structure is you will right click on two points that are going to basically make a 3d invisible box around what you want to protect. So, obviously, you would select the opposite opposing corners ( kitty-corner). Kind of like how you measure a TV or computer moniter but in a more of a 3D aspect.
So, now that you have selected your "cuboid" or invisible 3d box to manipulate you will type the "/protect" command. This goes as such: "/protect <yournamehere> <nameobjectwhatever>" ... or in my case "/protect last_305 monkeyturdsonyourface."
Okay, all done. I will write up a more detailed thread sometime in the future for those that need a little help.
