Claiming Land
YuriCraft comes with the GriefPrevention "claim land" system. In this system you can claim a specific number of blocks (that go from the lowest bedrock to the highest air block).
Claimed land allows you to "own" land on the YuriCraft server that other users aren't allowed to operate switches, levers, doors, gates, chests, crafting materials, etc. with.
The entire spawn area of YuriCraft is claimed with an adminstrative claim along with any central YuriCraft quest areas.
How to Claim Land
You should automatically claim your first piece of land when you place a chest. However, you can manually claim land with the /claim command and with a golden shovel.
Any land that isn't claimed can be changed or accessed by others. If you're building something you want to save, please claim it.
Resizing a Claim
To resize a claim, while standing on the ground, equip a golden shovel. You'll see glowstone in the ground. Right click that with your shovel to move the claim.
Giving Permissions
Use the /trust command to grant others rights to your claim.
Spawn Editing
Trusted builders can get rights to edit spawn.
