What is a Server?
A server groups up channels (chatrooms), usually by a group of friends. For example, you can create a server for a faction, team survival groups, etc. Minecraft servers can also automatically create a server for teams in minigames, which currently requires extension, but the server attaching feature will come in the future.
How to Create a Server? You can create a server with /minecord create <name> <description> <approvement> <invitation>, and join with /minecord join <server-name>
