- At the top of the navigation, click Admin.
- Then select Users and Permissions in the dropdown.
- You can invite new users by entering their email and choosing a permission level (permissions dictate what a user can see and do on the system, a more in-depth explanation here).
- Send it off.
You can always check to see if a user has signed up by reviewing your Invited User list in the left navigation. If they have not signed up, then their information will still be in the list.
