My Submission Status says "submitted", but below that it says that my Application Status is "completed."
I suspect the former means the applicant has hit the submit button on his or her application and the latter means that all of the various components of the application (transcripts, GMAT score, application fee, two recommendations, etc.) have been received. I can actually see when each component of my application was received.
I hope that helps.
I missed a call from a 603 area code on 12/30/10. I did a double take before realizing I was more than a month away from decisions being released. The caller didn't leave a message and the number was unlisted, but I'm pretty sure it was just Dawna Clarke calling to wish me an early Happy New Year.
