I was on the same boat last month and I quickly realized that their previous emails went in my junk folder (which auto deletes every week or so). I gave the IT people a phone call and they gave me a new password to quickly login.
Hope this helps
cGPA: 3.67, L2/B3 is basically the same as the overall GPA as my grades were consistent
EC's: Not that many, mostly internships and then work after graduating
References: Good. One from my thesis advisor in undergrad and one from my current employer.
I am in the same boat except that I applied to the French common law program. It's been three weeks and I haven't received a confirmation or UOZone info. Emailed comlaw yesterday, no answer yet but it hasn't been that long. Hope they get back to you soon!
