Go to "Company Settings" > "Company users". On the right-hand side, you will see all the company users. As an admin user of the company, you can add as many users as you wish by writing the e-mail addresses one by one into the e-mail address field, selecting the needed level of access and clicking "Invite". An invitation message with a link to login page will be sent to the e-mail address immediately.
The admin user can also remove users (NB: including himself/herself and other admin users), change their access rights by selecting the action on right side of the user row.
Admin user can also initiate password reset for the user (also under actions menu).
