I think the best thing to do is to keep an eye on everyhting.

My CIC, ECAS, both emails, phone. You'll never know. Like, my medical instructions came to my cic but with my husbands information (his email, phone number. And I never seem to get emails saying I have a msg in my account.
Also, sometimes they're running pilot projects as they were doing with phone interviews a while ago.
Well, I'm super anxious, so I just check everything everyday =P
@Kunlexy super interesting this "Permanent Residence Authorized". May I ask what was the letter about?
