It is not clear to what date you can register for the match. I would think ROL deadline would be the last date for which you can register (ie, Feb 21, 2002).
However, hopefully someone will supply you with a list of unfilled programs and you can get the information you need there rather than paying NRMP for the list (which will be at least the base price + $50 for registering late).
Most programs which have unfilled spots which they desire to fill (ie, aren't saved for someone else, or not being filled) will continue to fill those after the first few days of the scramble. Your chances of obtaining a spot dwindle as days post-scramble drag on, but if spots are still open, you are still eligible for them.
Best of luck. BTW, none of my business, but it would seem to be more prudent to wait out a year, doing research or whatever, than take your chances at scrambling into a program you know nothing about (not having been to the place, met the residents, faculty, etc.). Most of these scramble matches are made over the phone; you usually aren't given days to come for a visit, etc. Obviously if you HAVE to scramble then you have no choice, but without having gone on the interview trail, you have no comparison to make, no experience in looking at residency programs, etc.
