When you originally share for review and enter in the others with whom you want to share it, it allows you to send a note too. If updates are done, it doesn't notify anyone that the update is now on line and there's no box to send them a message that it has.

I would like it to send to everyone on the list a notice that the file has been updating and/or allow the message box to be there so I could at least manually notify them. The way it's set up now, I have to craft an additional email telling them to look at the file and if it's password protected, they can't even access it from the email so I have to unprotected it.
