On the "Firm Administration" page, click on the "Firm Settings" tab and activate your profile on the Network by clicking the “Publish Profile” button.
Until you publish your profile, you’ll only have access to your firm's profile and will not be able to see any other profiles on the Network. Once you’ve published your profile, you'll gain access to all other published profiles as soon as the search function is launched; you can then continue editing as necessary.
