Towny

The Towny plugin allows players to form towns alongside most economy plugins. In a manner that is somewhat similar to the factions plugin, players can claim 16*16 plots of land in which they have grief protection, toggable explosions, fire spreading, and mob spawning, and optional PvP. The number of plots you can claim corresponds directly with the number of people you have in your town.

Towny Info/Guide
If you would like to protect your builds or have a nice little protected community, creating a town is just the thing to do.

On Sedex, it costs $300 to create a town, $25 to claim plots of land, and $10 for daily upkeep. Generally, you want at least 400 dollars before starting a town so that you use the $300 dollars to create it, deposit $50 dollars into the town bank to keep it up for a while so that you can Make Money, and have the ability to claim at least 2 plots of land.

There are several different ranks that are entirely set apart from the Server Ranking System.

When you create a town, you are the mayor. The mayor has access to all the Commands that come with towny, besides the administrator commands. You have the ability to rank people up, add new people to the town, claim plots of land and outposts, and set the town homeblock and spawn. You can also change the town name, make somebody else the mayor of the town, and change the town permissions(Allowing Mobs to Spawn, toggling pvp, etc.)
