@wolframkriesing we will hire a barista who will bring cups. We are calculating with 50 people per day, 100 in total. Is that up to date? In addition we could bring some of our Peerigon cups as well.

@Lisa-Giese please see https://jscraftcamp.org/participants/stats for up-to-date statistics of how many registered people we have. I suspect we'll get to 100 people again on both days since there is still time to register and we have about 70 per day right now.
