I started an attempt for a european meetup of Discourse operators at the CCC congress (39C3) last year with this topic

[Discourse Meetup at CCC Congress in Hamburg?](https://meta.discourse.org/t/discourse-meetup-at-ccc-congress-in-hamburg/389731)

Unfortunately responses were limited. Maybe my request was a bit too late then, but let’s try again: the call for the 2026 congress “40C3” is out now and the location will have more space as they are moving from the CCH congress center to the Hamburg Messe at [https://www.hamburg.de/freizeit/maerkte-und-messen/messen/messehallen-323044](https://www.hamburg.de/freizeit/maerkte-und-messen/messen/messehallen-323044)

This is the official call for participitation:
