I talked to someone in the Graduate Admissions office yesterday via phone and he said that the way MICA's funding works can be summed up like this: "everybody gets some, nobody gets it all"
He said that they would offer 1/4 and 1/2 fellowships to most incoming Grad students - but no one gets a full ride. I e-mailed Chris Harring (I believe he was the one who was making the acceptance calls) and he pretty much told me that there is no other funding available through MICA for Grad students, but he did encourage me to look into outside/private avenues.
