In Docketbook, users manage their own accounts. It's the invitation process (Users) that controls whether you can see dockets within a company. Inviting a user doesn't automatically create their user account (unless they are a single sign-on client). The user will still be required to 'Create an Account', set their password, then verify the account email (or phone) before continuing.
Anyone can register for a free user account to receive dockets, or to connect with companies to receive jobs, or to become a user of a company. Whatever your job is to be done, signing up for your Docketbook user account is your first step.
You can use your email address (preferred) or your mobile phone number.
After you create the account you will be sent a verification message. Make sure you check your spam folders and then click on the link to verify your account.
