Lock allows you to lock chests, doors, furnaces and more!
/cpublic - Creates a public protection Anyone can use a Public protection, but no one can protect it.
/cprivate - Create a private protection Private means private: you can also allow other users or groups to access the block as well. This is done by adding them after "private". You can add more than one group and/or user per command. When you prefix a User or Group with an '@', this User/Group will be able to modify the block and add other users. They cannot disable the owner from modifying it.
/cpassword - Password-protect a block Each time you login you need to enter the password to access it (if someone else knows the password, they can access it too).
/cmodify - Modify an existing protection, adding or removing users and/or groups. See /lwc create, the example for private protections. The same syntax is used for this command. There's an additional prefix however. Writing a '-' infront of a User or Group removes the access from the block.
Example: /cmodify -User1 @someguy - removes access to the block for User1 and gives SomeGuy advanced privileges /cmodify town:SomeTown - grants access to the block for all members of SomeTown (Note: Tested with Towny)
/cunlock - Unlock a password-protected block
/cinfo - Punch a protection to view information on it
/cremove - Removes protection from a block
/climits - View the amount of protections you are allowed to own
