I'm still waiting on Cambridge... i understand from posts on here that the university is still in the process of going through applications...

However, I was wondering if Cambridge emails you either with an acceptance or rejection once they've made a decision?

siggy,
I received notification of my offer a couple of days ago by email - I think they will make an effort to let you know as soon as they have decided either way (that's kind of what it says in the email), but it may take a while if it's solely the course secretary's job to notify everyone.
Good luck.
