No problem guys. Don't freak out if the school doesn't get back to you for a while after your application is complete. I'm a Fl resident and I submitted my secondary to UMSM in October '03 and didnt get an interview invite from them until April '04, six months! I had pretty much written them off, I'm just glad they hadn't forgotten about me! =) UMSM admissions is just very selective with interview invites but once you get an interview, you're chances of being offered a spot in the freshman class are very high.
Its a great med school, classs started on Aug 9th and I haven't heard anyone in my class say that they regret the choice.
If any of you have any questions about the school or interview, just PM me. Good luck!
