  Two New Important Updates to Google Slides

Google today announced it has tweaked the way sharing works for Docs, Slides and Drawings. Recipients no longer have to sign in or create a Google account if they don’t have one.
This is particularly useful for Google Apps customers looking to share files outside of their domain. If the recipient does not have an email address linked to an existing Google Account, he or she will still be able to view the document in question without taking any extra steps.
If a file is shared with edit or comment permissions, however, the receiving user must still sign in with a Google Account in order to edit or comment on that file. In other words, signing in is now optional as long as the file in question is directly shared with the recipient but comes with no other requirements.
