Hey, I guess you know the meaning of organizing such meet-ups in Switzerland. The rule is quite simple, we get more than 7 people who are motivated to participate in a BTS meeting/workshop/party and we go!! Now it is already ONE. We could fix the details like the exact time and place, the form of the meet-up, etc... when we got enough signups. I will be glad to help coordinate.
Please reply if you are interested in a meet-up in Switzerland.
