To access the list of current organization members click on the gear icon in the upper left corner, then go to "Organization settings".
You will see a table with all your organization's members, including their names, roles, and the date they joined.
Also, you can see if somebody hasn't accepted their invitation yet and you can resend the invite.
Other available actions by clicking on the three dots "..." icon on each row:
Update email - in the eventuality of an email change you can update a member's email. They will be able to use it immediately after to log in.
Suspend account - you can choose to suspend members, for example, if they are no longer part of your organization, and this will prevent them from logging in again. No worries, the content they have created, including items and/or comments is still kept in place.
