This feature makes life cumbersome for us. Change the email address under the client screen.  It's not good that it doesn't go to both and only ONE name appears when it's a joint return.  It looks sloppy on our part.  There is only one sign on for link for both taxpayer and spouse.  They must share.  It makes something that should be simplistic into something that's time consuming because we have to customize and think...Do I work with the main taxpayer or the spouse.
