My Hours PRO and PRO trial accounts are able to add team members.
You can add your team members by going to 'Manage' --> 'Team members'.
You can add a new team member by clicking on a green 'Add New Team member' button. After you fill in the information and click on the 'Save' button, your team member will receive an e-mail with the sign in information.
By clicking on a particular team member you will later be able to edit their personal settings and hourly rate.
