Archiving helps you keep your Dashboard organized and save inactive Campaigns, Segments and Nuggets for later use.
To Archive a Campaign, Segment or Nugget, simply open the Edit menu, and choose Archive.
You will see a new menu appear at the top of the screen, where you can choose how to view your list (unarchived, only archived, or all).
To unarchive an element, enter the Archived view. Open the Edit menu, and choose Unarchive.
*Note that live Campaigns can't be archived.
