Hi there! I'm a German physics student at LMU Munich and might be interested in the meetup. It's just...I'm shy, have never been to any kind of meetup, and have no idea what to expect. So...what can I expect? How many people typically show up? How many showed up last time?

And I read there might be a Facebook group - if there is, how can I join it?

EDIT: Found and joined the Facebook group here. I'll participate.
