1. From your main dashboard, select “Contacts” on the top toolbar. This brings you to the main contact page (List View).
  2. Find the blue header links below the calendar. Clicking one of these links (e.g. “last updated” or “date added”) will re-sort your contact list into the order you selected for. 
  3. Clicking the “First” or “Last” blue headers in the left-hand column will sort your contact list in alphabetical or reverse alphabetical order.
  4. Clicking the blue headers in the middle column allows you to sort your contact list by most recently contacted, date added to the system, or last updated.  If you hover over the corresponding information in the middle column you will be shown the specific date/time the contact was updated or added.
