As an administrator you can assign roles and responsibilities to other users, a.k.a you’re the leader of the herd. He or she can create roles like ‘Marketing Team’ or ‘Merino Lovers’ and decide who can do what. A basic (or public) user doesn't need to have an account to use Sheprd. For example, he or she may be authorized to download files.
When you're an administrator (or another role with rights to alter user's roles), open your user settings.
Assign roles to different users, and tick the boxes of all the rights they have, what files they can access and transfer.
Here, you can also resend an invitation link or reset a user's password.
