To access a space on a desktop browser, you need an invitation, which includes the following:
URL: Typically, it looks like this: https://nnhub.cloud/012-3456-789.
Six-digit PIN: This is the space's passcode.
Once you have those, here's how to join a space:
Enter the space's URL in your browser's address bar.
Sign into NodesNow or register for an account.
Select Join the space as a participant.
Enter your display name and the space's security PIN.
You'll then be taken to the space, where you can begin collaborating.
