How can the affiliates order campaigns by date in descending order?

If an affiliate wishes to order the campaign by date so the list starts from the newest one then the following steps need to be taken:
  1. While being at the Campaigns screen  click the "Edit view" link right above the grid listing the campaigns
  2. Check the check-box next to  "Date added
  3. Rename the view name to something else (e.g. Default v. + Date added)
  4. Click "Save"
From this time on you will see also the "Date added" column and if you click its header (the 'Date added' title), then the order of campaigns will change. 
 
Once the campaigns are ordered by date in descending order and the affiliate wishes to save this view, then he has to click the "Edit view" again and click "Save". 
From this time on whenever the affiliate accesses the Campaigns screen the campaigns will be ordered by date in descending order.
