We call it ‘writing’ in New Zealand. I think Australians refer to it as ‘pencilling’.
I am a writer convenor for a few dressage groups/venues in New Zealand (so much so that I have a dedicated writerconvenor email).
I LOVE writing. You get to see so much that the judge gets to see. Back in the day when scorers worked out results with pen, paper, and calculators you would hear riders exclaim “why is there such a difference in my scores between judges?!” when standing at the scoreboards. Sit at E/B or M/H and oh-my-gosh what a different perspective!!
Shows can’t go ahead without volunteers (we do get a wee $ contribution, fed and watered) so why not put something back into the sport? I have a ‘how to’ that I send to new writers.
Please just ask your show secretary/event manager how to write, even just for an hour at a local day, they’ll love you for it!
