Last weekend there was a tremendous event for LibreOffice hackers in Münich. . More than 30 people joining for some days and working on features, bugs, UX (and pasta ..)
It's obvious that there is a great base of LibreOffice users and devs in Germany (and Italy ;-) )
What about The Netherlands and Flanders? We had some small events already last year. With between 5 to 10 people joining and learning about, cooperating on localisation, development, features..
The next Saturday we have a new event planned. In the science city of Eindhoven. We also invite the old friends from OOo to share about all that's going on and cooperation. More on the wiki .
