/cpublic - Creates a public protection
Alias of: /lwc -create public or /lwc -c public
Anyone can use a Public protection, but no one can protect it.

/cprivate - Create a private protection
Alias of: /lwc -create private or /lwc -c private
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.

Example:
/lwc -c private Username g:Groupname @username2
/cprivate Username g:Groupname @username2

/cpassword - Password-protect a block
Alias of: /lwc -create password or /lwc -c password
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.
Alias of /lwc -modify or /lwc -m
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:
/lwc -m -g:Members - removes access to the chest for all Members
/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
Alias of: /lwc -unlock or /lwc -u

/cinfo - Punch a protection to view information on it
Alias of /lwc -info or /lwc -i

/cremove - Removes protection from a block
Alias of /lwc -remove or /lwc -r

/climits - View the amount of protections you are allowed to own
Alias of /lwc -info limits or /lwc -i limits
