I'm in the same boat as you, Jack: admitted with an MA but no word on funding yet. Just a couple letters from the graduate school and the dean.
I spoke with the DGS over the phone several weeks ago and didn't leave the conversation with any hard numbers, just a hopeful hint that something more than what they have listed on the website might be available. Looking at their section on funding, it appears to be 14,000/yr for three years, but I really, really, really hope that it works out to be more than that. It would be nice to know up front that dissertation support (in $$$, of course) would be guaranteed for the last year.
Hopefully they'll put out these details to folks soon. Real soon.
Any knowledge of visiting days?
