Hi Petr,
In that case i would say that we just present our project without doing a workshop. That will be fine!
Also, as you can read on the details of our site, one of the main parts of our project consist on documenting the different hackerspaces we visit along our trip, that is why we would like to ask you if it would be ok for you if we realize a small and informal interview with some of the members of the space and film it in order to publish it on our website.
The idea would be that we ask you a couple of questions about how the place is organized, what kind of projects are you guys running there and how you are contributing to share knowledge with others. What do you think about it? Would somebody of you like to do this? Should we maybe show up a bit earlier so we can do it before the talkNight begins? It doesn't need to be really fancy, just informative...
Looking forward to receiving your answer on this regard,
Greetings from Berlin,
Alex.
