1.  Locate your list of Active Campaigns from your Manager Dashboard.  In the top right corner you should see a green "Add Campaign" button.

2.  Name your campaign (Location and description are optional).  

3.  Under Setup Type ALWAYS select "copy configuration from an existing campaign."  Then, select the campaign from which you would like your settings copied over.  This will bring over all dispositions, custom fields, permissions, etc... into your new campaign.  Otherwise, you will be left with a blank shell.
