Hi Ray Menzies,
Reviewing through your description you might find the Profile Completion report, available through the Community Manager Report's feature provides this type of information, as it includes "last login" and "member since" information (Analytics ). Alternatively, if you are interested in developing a report that includes a list of users sorted on creation date you might find the following documents helpful
Lastly, if you would like assistance developing a custom reporting option for your instance I would suggest engaging with our Professional Service team, who can work with you to determine the scope of the project and assist with its development. If you are interested in this option please submit a case in your customer group ( MyJive Secret Support Group Administration FAQ ) as a next step where a member of our support team can get an engagement started on your behalf.
