I noticed that the #ChatMail relays have a `/metrics` page that lists the number of active users. This info is gathered through a cron job. So I decided to poll the known public servers every hour and see how large is the user-base of #DeltaChat on public servers and how does it fluctuates. I will publish the results in a few days when enough data is gathered, but for now, the code lives in this Git repo and any ideas/suggestions are very welcome:
