When trusting people to your claim, you have to chose where and how much trust they have. To trust someone in your claim / subdivision, you have to stand inside and use /trust (Player) [TrustType] (() means obligatory and [] optional, without specifying trust type, it will be Builder)
Accessor: gives access to buttons, levers, fences, hand cranks, valves, etc
Container: Accessor + gives access to blocks that contain items, such us chests, cabinets or a mechanical belt.
**Builder: **all the above + you can break/place blocks
Manager: all the above + can manage the claim and its trusts, same as owner but can't delete the claim
Resident: Accessor + can make claims inside. Only works for Town claims, and the town owner can decide how many claims and its size for residents to have.
Hint: Using public instead of a player name will make that trust to everyone!
