If you plan to be the primary account owner of the membership, to create a new Spotter Studio membership, visit spotterstudio.com and click "Get Started". From there, you will be taken through the Google account authentication flow.
FOR NEW SUBSCRIBERS: It is very important that you authenticate with the same Google account that is linked to the YouTube channel you want to access within Spotter Studio.
If you are a team member associated with an existing channel/membership, once an account owner or admin invites you to join their membership, you will recieve an invitation to your Gmail with instructions on how to activate and access your Spotter Studio account.
