Hi Karl,
in the group - Subscription - Settings, look at the ?Moderator notifications¡° . Under ?Members¡°, you can define what should happen when a new member joins the group or when an existing member leaves the group. I suspect (haven¡®t tested it), that if that is set to notify moderators via email and web, all moderators should receive at least a message when a new member joins. Can¡®t test if that¡®s true also if someone joins by direct invitation. Maybe that option is set to ?None¡° in your group? Then of course no moderator receives an information about a new member joining by direct invitation.
Kind regards
Thomas
