I need a protction plugin

Hi. I have my server but it needs a protection plugin. I've tried quite a few. I've been trying to figure out what this one plugin was called. It has alot of comands like /rp am or /rp ao for adding members or owners to your protection. Can someone tell me what the plugin is called or something alike to that? You see I'm not good with all kinds of technical commands and stuff so...


Note: For my server I want a thing so I can protect buildings for the players on my server.

Does anyone know a nice plugin like that??? Plz help!
