Sharing the list of open programs is against SDN rules prior to the end of the SOAP
That information is for people who paid and participated in the match but didn't obtain a position. If you are in this category, you will be provided that information by the NRMP.
If you honestly forgot to register for the match, then once the SOAP is over, you can get a list of still open programs. You are not eligible for the SOAP if you didn't register already.
