Google Sharing Allows Expiration Dates #gafe #googledrive

A new feature (I think) a colleague pointed out today is pretty cool in that it allows you to share something in Google drive only for a specific timeframe.  After you choose who to share a document with a little clock appears to the right of their name that allows you to set the expiration date.  There are obviously a lot of great uses for this, for example in the classroom to limit how long students can be in a document.  Great job Google.  Keep it up!
