We did get a response to our CSE saying that they had got our email and had added it to our application, a week or 2 after we sent it. Not everyone gets that, though. I know it's hair-raising, but the only thing to do once you have sent the new ECA is wait - the longer the wait, the less likely they will cancel you over it. You see they didn't cancel us, and it took us almost 3 weeks to get the new one and another week or two for CIC to acknowledge it. Not only that, but my partner's school will not send transcripts directly, so we had to forfeit his 8 points for education. We were still within our draw, though, and I mentioned that in my letter with my new ECA - and it was fine, as you can see.
Yes! We got PPR last night. I am already in Canada, but to earn a little extra money I edit a small newsletter in Slovakia, and that involves having to get up every morning at 1 AM to do about 20 minutes of editing before falling back asleep. Last night, PPR was in my inbox along with the editing! I couldn't go back to sleep after seeing it, and we ended up having cookies and milk in the living room as a celebration, falling asleep again around 3:30 AM. It's a wonderful feeling!
