Networks are great if you plan to manage multiple podcasts under your brand. They also allow you to invite users to help you manage them.
During Early Access you can create a network by logging in to the Podcast.co Online Studio. Hover over your name in the upper right of the page then click 'Create New Network'.
You will be invited to give your Network a name. This will be visible to anyone you invite to manage your podcasts, however it will not be publicly visible on your podcast feed in directories.
Then you'll need to name your new Podcast Network. Once you've typed in your new name and you're happy with it, click Create. You'll be redirected to your collaborators page, where you can add, remove, and adjust the restrictions of your collaborators.
You can find out more about Collaborators here.
