Each colony has a single owner. The owner is called a "Colonist" and has access to the following extra commands:
/addmember [region] [username]
| ||Adds a player to your region. The region name for a colony is usually called "colony_yourname". But you can use the /checkname command to see what your colony region is named.|
/delmember [region] [username]
| ||Remove a player from your region.|
| ||List all members of your region.|
| ||Check the names of all regions you own that you are currently standing in.
If you want to know the name of your colony, go inside your colony and use this command.
