Due to technical problems with a new computerized pairing system, the first session of the 2003 ASICS/Vaughan Cadet National Greco-Roman Championship in Fargo, N.D. on Saturday, July 19 was cancelled.    The morning session was scheduled for 9:00 a.m. Central time. When it became clear that the tournament operation was not ready to go, the session was postponed.     The action was rescheduled for 1:00 p.m. and arrangements were made to correct the problem and begin the tournament at that time.     Action has now begun on the 23 mats. Results will be posted when available.    Session times will be adjusted and mat assignments revised in order to make up the time and complete the tournament as scheduled.    There were 951 entries in the Cadet Greco-Roman tournament this year.
