# Register with organisation invitation

Once your organisation admin user invites you to join the organisation account, you will receive an email notification. Click **Start using service**.

If you already have a SignSpace account, **do not register again**. Use the **sign in** link in the blue notification at the top of the registration form.

If you do not have a SignSpace account yet, fill in the registration form and click **Continue**. Follow the guided workflow to join the organisation.
