How am I able to extract the number of active users in our system by month for last year?
From the menu bar at the side, select Site Administration. Click onto the the following: Users tab, Accounts, Browse List of Users then the Show More button.
Change the date to be the date range desired (eg: 90 days (3 months)) from the present date or use the is before and after date filters to input custom date ranges desired.
Scroll to the bottom of the filters section and select the Add Filter button
