Hello Chris, On my part there is no problem next week, I propose to define the day from Wednesday.
My location is GMT-4, take it into account. And my internet connection is really bad :-). I will try to document as much as I can to share with the team. Best regards, El jue., 6 feb. 2020 a las 4:01, Christofer Dutz (<christofer.d...@c-ware.de>) escribió: > Wow this is great stuff!!!! > > Sorry for not responding yesterday.
