applicant services?

<p>i wanted to log on to see what stuff NU has received from me, but I have no memory of ever having an application i.d. number. I requested that they send it to my email, but they said they had no i.d. for that address...unfortunately, that address is definitely the only one i use, so there's no chance that they have me registered under a different one. when did we get assigned app i.d.'s? and any ideas on how to track mine down?</p>
