[pypy-dev] Düsseldorf sprint at the end of august?

Hi all, I know that there is a vague plan to have a sprint in Düsseldorf in the last week of august, on time with the end of Eurostars. Can we make it more concrete, decided the dates, and announce it, please? It's very likely that I'll go on vacation in the 3rd week of august, thus it would be nice to know the dates to do a proper travel plan. ciao, Anto
