That's not my name

I'm interviewing at Program That Shall Not Be Named this Friday. And minus the very first interview request email, all of the follow-up emails have addressed me by a different name. Dear Melissa. Dear Ms. Lupsa. Dear Dr. Tung.

So now the real question is, when I show up this Friday, what name do I check in with? Because frankly, I have a real fear that my real name might not be on the list anymore. I'm very strongly tempted to introduce myself as "Hi, I'm Melissa Tung Lupsa - but all my friends call me Michelle."

Actually, now that I think about it, the first interview request email just addressed me as "2010 Interview Applicant."
