There are two ways to copy a page or a collection.
1. When you know the web address of the page or collection you want to copy
Log in to workflow and visit the page you want to copy
Click on the menu icon (or type M for menu on your keyboard) to bring down the menu bar
If the page is copyable, there will be a Copy button in the menu bar
Click on Copy
If your page is part of a collection, you will be asked if you want to copy the individual page or the whole collection
When you make your choice you are taken to an interface where you can edit the title of your new page or collection
2. When you DON'T know the web address of the page or collection you want to copy
Go to My Pages -> Pages (or alternatively My Pages -> Collections)
Click on the Copy a Page button (or alternatively the Copy a Collection button)
Search for the page or collection to copy by typing in a search keyword, or searching by the original page author
When you find the item to be copied, click on the Copy Page button or the Copy Collection button
You are taken to an interface where you can edit the title of your new page or collection
Please note, for a page to be copyable, it must have been shared with you, and must have been set to be copyable by its original author. See the how-to guide, How to Make Your Page or Collection Copyable The only exception is your own pages - you can copy any of them.
