Can I Add Other Folks (with their own node) To My Network?
This is pretty much the easiest thing you will ever do. Click on the <Add User> box in the Users section and enter their email address, node limit, and permission level:
The person you wish to add will receive an email inviting them to your network with complete instructions on how to do so. (essentially the same process you went through - create a login and spin up a node).
Once they have completed the process, they will appear in your admin console.
