I was checking out a server last month, and they had an awesome plug-in!!!!
It's called; Factions
It was designed for war servers, but you don't have to use it that way
"This plugin will allow the players on the server to create factions/guilds. The factions can claim territory that will be protected from non-members. Factions can forge alliances and declare themselves enemies with others. Land may be taken from other factions through war. Also the more members you have, the more territory you can claim"
But as I said, war isn't necessary.
So why do I want this plugin to be in this server?
Good question, It protects my property, people cant destroy stuff or open doors and chests in someones territory. And of coarse its awesome to have a big clan with lots of members and lots of territory.
What do you say about it guys?
if anyone is still active on the forum :S
