Hello again,
In terms of my notification - I just received an email on Monday. It was from the DGS, and said "congrats" etc. It mentioned some of the strides being made in the dept. in recent years. Also, touched upon things like funding, stipend, etc. Finally, it mentioned the "admit visit day" in early March, I believe, and offerred an invitation to attend.
I did not have an interview. During the application process I did email several profs discussing my interests. Also, I sent an email after submitting my application to ask when a decision could be expected.
To everyone who has heard good news from all over - Congrats. To those waiting - be patient and good luck! I wish much success and happiness to all of us in our grad-school pursuits.!!
