Hi and welcome 
welcome to our home on the Internets
Yes the bunk beds are still available. I would like for them to support people with complementary aims/interests with the Edgeryders already going…
Do you know what you are aiming to learn/build/find/do at the event?
Maybe we can help each other. I think Dan pointed out so well what it is we are trying to achieve together here: https://edgeryders.eu/en/agora/if-you-meet-the-expert-on-the-road-kill-her.
Personally I am passionate about building Harmonious Hackathons as a p2p support infrastructure for meaningful, beautiful and clever projects that are valuable whether or not the market can regognise them as such. One theme is that of hacking well-being and care. We did a session about it at the last community event in October and it would be great to carry that work forward.
Maybe have a look at the notes and see what you think we could do at 31C3 and if/how you could help? https://edgeryders.eu/en/lote4/notes-from-the-lote4-session-on-the-future-of-care-in-the-hands
