Step 1: Have the user in question create an account here
Step 2: Log into your Multicraft account and open up the main control page for your Minecraft server.
Step 3: On the left-hand menu, expand the Advanced tab and click on Users.
Step 4: Search for the username which your sub-user registered.
Step 5: Click on the No Access and Unassigned tabs and apply permissions accordingly.
Step 6: Your sub-user will now have access to control your Minecraft server.
