You must create a user account in order to view living individuals in the family trees.  This process is not automatic, you have to be manually approved by the site administrator.  To set up the account:

  1. Select your family tree from the main menu.
  2. Select the Login link in the upper right of the family tree window.
  3. Select "Request new user account" from the Login screen.
  4. Fill in the information form.
    Family Tree signup form
  5. After you submit the form, you will receive an email, click the link in the email to complete the registration process.
  6. I will also get an email and I will grant access to the family trees if appropriate.

What could be simpler?
