You will see a follow icon on every creator's page. Click that, and you'll be able to see any of the creator's publicly-facing posts directly from your home page. If you'd like to unfollow the creator just click the following icon, you should see that following reverts back to the option to follow.
If you don't see a follow icon that's because you're currently a patron to the creator! If you delete your pledge, you will then see a follow icon.
If the creator you are following reverts to a patron-only account, you will not be able to unfollow them, but you will also not receive any notifications from their posts, unless they become a creator again.
