From the acceptance e-mail from Edward Tom:
You will note that our website has an administrative page reserved for new admits. You will be able to access this area in early April. Among other things, you will be able to access and view your financial aid offer and to complete various registration forms. The area will be password-protected and will require that you have a student identification number (SID) and a personal identification number (PIN). These numbers will be generated at the conclusion of our admission process and we will send them to you at the earliest possible date.
I haven't received any other info about the admitted students' site.
