if you hold a contest for years and years, but the results never get published, in the future will anyone know they even existed?
I've made many requests to the WPF for previous contest results. They supposedly have been holding a Universe every year since 1989, and they think they're a major player. The only year I was able to get results from their website (which is now gone), it contained so many misspellings, and only gave first initials. One rather well known European female athlete had her name spelled 3 significantly different ways in 3 different classes.
if athletes go to all that effort to enter your contest, you should make the effort to report the results.
