Players can claim up to 200 chunks of land. Claiming land is easiest when done on the world map. You can open the map up using the 'm' key and then right click on a chunk and select “claim selected.” Claiming your land will help prevent griefing from both players and mobs. Claims expire after 365 days of player inactivity. The mod responsible for claims on the server is the Open Parties and Claims mod. You can keybind the configuration menu using the ' key.
