If your new agent or manager created a profile for you, you will get an email to notify you. After clicking I have an existing account you can log in to associate this new profile to your account.
If you do not yet have a Casting Networks account, after clicking I need to create an account button in your email invite. Click Register to create your free Casting Networks account.
If you have multiple profiles, you will see a profile switcher on Your Profile showing your personal profile and/or any represented profiles you have. Click on the switcher to select a profile and make any necessary changes or updates.
