If you know of a NSS Racing event currently not on the Calendar, it is very simple to add and have your event available to Search Engines to index for more Racers and spectators.
The calendar is posted at the bottom of each page in the NSS Racing Forums, and there is a channel to add events that are not yet on the Calendar.
Get your NSS Racing information from a web site specializing in promoting the class, and not an unorganized social media group.
