Organization member settings
View the list of all the members belonging to your organization under the Members section of the Organization settings. If you have admin access, you can edit member roles from here.
Click on members to view their details, edit their roles or remove them.
Invite new users to your organization by clicking the Invite members option. Enter their email addresses and click Invite. They will join the organization after accepting the invitation sent via email. When users join an org, their default role will be 'Org Member', which you can change anytime.
You can have only one Org admin but multiple Org moderators.
