If you're planning to take a closer look at FLOW3 and live in Switzerland or Southern Germany, there's a great opportunity for you to delve right into essentials: I'll give a one day public training in Zürich this September.
The full-day workshop will leave you with a comprehensive overview of all essential parts of FLOW3 and gives you enough information for your next steps. As FLOW3 1.0 is right around the corner, there is probably no more effective way to get started in time.
snowflake productions organizes the event. The session is held in German (well, no Swiss German, I'm afraid) and you better be quick with signing up if you want to catch the early bird price.
All further information can be found on the snowflake website.
