Server Access works as follows:

• How to Join –  (Step 1) You have to get whitelisted to look around and see if you like the server.
• Building Rights (Become a Settler) – (Step 2) Then you can apply for a 128×128 blocks protected area, where you can build and be protected. Your chests will be protected, and no-one can build or destroy anything on your lot. You will then also be able to use all the other features of Uncovery Minecraft
• You can build in the darklands world and the nether after you become settler. See worlds information page for more info.
