Got mine as well just a few hours after I asked! Submitted my campus preference at around 6:00 pm, and I got my assignment just 20 minutes later. I'm going to be in Savannah for all 4 years!
I second your question; could any current students weigh in? I'd guess not, as I think that we are required to sign and submit that form in order to formally accept our place in the class, and lots of Mercer graduates don't go on to practice in an underserved part of Georgia or in a core specialty.
Mine was definitely fillable, so you should probably email the admissions office. Your ability to convert it to a fillable pdf will probably depend on the program that you're using. I think there's a google chrome extension that can do that. If I were you, though, I'd just contact the admissions office, honestly.
