Sharing Google Documents with People Outside of Stony Brook University

To share with someone that does not have a Stony Brook University Google Account, find out if the person has a Google Account. If they do, share with that email address. If not, they can create a Google Account (even with an @yahoo.com, @aol.com, or other email address), or you can consider changing the item's visibility to Anyone with the link while that person needs to access the file.
