Sharing with your entire Institution
To share with your entire institution, you'll need to navigate to the Sharing options page. Click the Media options button for the file you want to share, then click "Share."
This will take you to the Sharing options page.
The third sharing option in the drop down menu is "Share with all Warpwire Account users (Institution)." If you choose this option, anyone who has an institutional sign on can log in and view your media file.
