Appears to be a week in August/October (TBA, added a random date for it) co-living/working on this project. As I mentioned on the IRC channels, I think it will be good to build relationships with these people and support the Yunohost project which has so much potential (and already is a great success).
If anyone wants to join, let’s chat!
Here’s a more official invitation, now that the dates are frozen 
Hello !
From August 10th to 16th, we are organizing the Brique Camp / YunoCamp 2019, an event during which contributors from the YunoHost and Internet Cube projects meet and work together. It will happen at the Fuz hackerspace in Paris (easily accessible from the metro, near station Nation).
You are very welcome if you want to join us - even to work on different projects (related to Internet decentralization, etc.) or just to discuss for a few minutes or hours ;P! Inside the YunoHost and Internet Cube projects, we have many important topics not requiring tech skills (such as redesigning the websites / landing pages, doing UX tests, helping to design stuff in the webadmin, having pedagogical documentation, …)
All infos are on the dedicated topic on our forum. (N.B. : if you plan to attend, it will very much help us if you add yourself in the framadate or send us an email!)
Cheers!
Aleks for the YunoHost team
