If I were you I would call/email the ROO at the school you chose. She/he will probably be just as interested in making sure your acceptance gets posted. I know if you were coming to Clarkson I would be on you like white on rice to get your acceptance (or at least know that you chose another program). You can also try bothering the 5 or 6 people that process 10000+ scholarships a year, but don't be surprised if they don't answer your email right away.
And the next step in the process will be receiving instructions for your DODMERB and whatever your new Battalion has planned for you. Some programs have an orientation. Some wait until you arrive on campus at the beginning of the school year to start the process. Once again I would try contacting the ROO.
