As we are writing this short introduction, it is exactly a year ago since we had to cancel our planned Training School, which was supposed to take place in late March 2020 in Tallinn, Estonia. 
It was the start of the Covid-19 pandemic, and we had no idea that the situation would remain critical for such a long time. 
Now, a year later, we have adapted to the situation by organizing our Working Groups’ Meetings online, and by starting what soon became a series of live webinars, each time hosted by one working group yet bringing together discussions across the entire network.
