Claims let other players see what's your land. Claim your base as soon as you settle down.
We use Open Parties and Claims (OPaC) for land claims and parties. Claims are made per chunk (16x16 blocks, the full height of the world).
If you picked Xaero's as your map when installing, open the world map, select the chunks you want, then right-click and choose Claim. This is the easiest way to claim a big area.
Press ' (apostrophe) to open the OPaC menu. From here you can manage your claims, your party and your settings.
Stand in the chunk you want and run:
/openpac-claims claim to claim it/openpac-claims unclaim to unclaim itA party lets your friends build and use things on your claims. If you're starting a town, make a party for it.
/openpac-parties create makes a party with you as the owner./openpac-parties invite <player> invites someone.You can also manage your party, ranks and allies from the OPaC menu (').
Every block placed or broken and every chest opened is logged. Open a ticket in Discord with where it happened and roughly when, and staff can look it up and roll it back.
For everything else OPaC can do, see the OPaC wiki.
