Enter in the info desired for the new user and assign them to a user profile from the select drop down box.
If you would like to assign a password to the user enter it in the field below. If you wish for them to create it themselves simply leave the field blank and they will setup their own password beginning from the email they will receive once you add the newly created user.
Once created you can go edit the user profile by clicking the edit button on the right side of the table on the main screen.
