From the Team Captain's Edit Page, you can select Invite Team Member.
Once the Team Member has received the invitation email, they'll need to select the link in the message. After selecting the link, they'll fill out a short form.
Filling out said form will confirm their acceptance of team membership.
Once the Team Member verifies an emailed code, they will be taken to edit their personal page.
NOTE: This page is also accessible for the user when they login into their personal Kindful User account.
