Auttomatic, the company that maintains WordPress, runs its own repository for open source plugins and reviews them before release in order to avoid security or juridical difficulties. I have now uploaded my first plugin there. It is a tournament registration script I developed for the site of my local chess club ESV Rot-Weiß Göttingen. Initially it was aimed towards tournament registration only but now it proves useful concerning the limited capacity of our playing venue due to COVID-19-induced social distancing. You can already view it in action (German).
