You will use Bulk Actions to download the list.

• Go to the People module on the left navigation menu to organize which of your Members you would like to download. You can download the entire list, or you can narrow the list to a particular set of your contacts by using the Select by Tag function. 
• Click each of the tiny boxes on the photos of the contacts you would like to download, or use the Select Current Page or Select All buttons.
• Once selected, the grayed-out Bulk Actions button will turn blue. Click it and choose Export to Excel or one of the other options.
