In JEDWare, you can create as many users as you want. Each user can be given a user role with customized accessibility. The user will receive an email upon creation to choose their own password.
Pending user creation can be found in the box placed below the user creation box. You can resend them a new email if the first one got lost, or delete a user that was created by mistake, and newer signed up.
