When you log into the Admin Area and navigate to the ‘People’ page, it will by default show a search bar. If you use the ‘Views’ at the top, you might notice you cannot see all the people you thought should have come up.
The reason for this is the ‘Filter’ option. By default, it will only show you active people. To view all people, simply change the filter settings to suit, or by clicking on the ‘Clear Filters’ button.
If you’re looking for someone specific, try using the search or Advanced Search feature.
