The Manager clicks on the new Netsso Group link on his My Groups panel, and from inside it he clicks Admin / Manage Netsso Group (or from the User Details area on the Netsso Group Blog page), and this brings up the following dialog
Inside this dialog he sees icons beside each existing member’s name, providing the member‘s email address, the ability to modify permissions, update the contact details or delete the member. At the top he sees a button to press to Add a New member, and he can also press the "Invited" button for a list of those members who have been invited and not yet responded.
When he clicks the "Invite user" button, he receives a new dialog, inviting him to enter the members email address (even if he is not currently a Netsso member). He can also type a message for the invited member, to be sent along with the invitation.
At this point- when inviting a new member- the Manager also has the possibility to set user permissions for the new member, or he can do it (modify them) later. (Read about Permissions below)
