If you have access to an Ankeri account via invitation from a registered Ankeri user, you will see the following when accessing the Settings section.
This means that you have access to an account on Ankeri on behalf of your company but your company still hasn't registered anyone to administer that account.
Without an administrator, anyone with access to email representing your company (same email domain) can sign up for access to your company's account.
If your company does not plan to add any ship profiles on Ankeri you can very well continue without registering an administrator although we highly encourage you to sign up for Free version of Ankeri.
To register an administrator to your company account with all the benefits it includes follow the instructions given on How to I sign up for a free account?.
