Private collections let you organize your pieces without the collection showing on your Social Blog.
This is perfect for organizing pieces in your library by category or you can even use private collections to optimize your workflow by creating a "Ready to Publish" or "In Review" collection.
To create a private collection:
Press "Collections" from the top bar on your "Social Blog" page.
Select "New Collection" and give it a name.
Toggle the "private" option to on.
Now you can add pieces to your private collection!
Note: published pieces in a private collection will still show on your Social Blog feed (but the collection will not be visible)
