Hey, I want that cool badge too, @Stefan!
I can meet in Madrid and Madrid area, Spain. I frequently visit Medialab Prado, which is a centric place for peer collaboration and workshops from the Madrid city council. It has OSM or Wikimedia groups, for example, and had a Mozilla group too.
But I’m more reachable online. I’m a frequent collaborator on the forum (trust level 4) since I got a FP2, I also manage the WeAreFairphone group in GitHub with @Stefan, whom I helped with that awesome map you see above, got my hands dirty trying to make FPOOS better and Google-less (#livingwogoogle) and porting LOS with awesome people + making microG easily installable, and I didn’t assist to any EFCT yet because I’m a terrible trips planner,
