Hi Maciej, welcome to Hive.
What a coincidence, we will have a Hive meet up in Krakow on 7th October. It will be the perfect opportunity for you to get to know Hive better and meet more people to make your Hive journey more enjoyable. There will be many of us coming from overseas, perhaps you can even arrange a tour for us to show off your beautiful city. The meet up information can be found here, it would be lovely if you can join us as these Hive meet ups don't happen all the time.
