Full Remote Plan Approved

On August 6, 2020, the board approved the following plan:

The entire NSML season will be conducted remotely, with as few changes as possible from the way seasons have been run in the past. Contest dates remain the same. The testing window will be 6-8pm. Orals will be conducted the day before the meet date. All details are available in an email to coaches. Dues for the season are reduced to $100.
