Slack is the main communications tool to co-create Schönburn. It is used by the Orga team, fellow Schönburners, leads and their teams, co-creators who have questions to each other. Use it to communicate with other participants and organise stuff!

Once you are in Slack, click on the word Channels to the left. It will show you all channels you can join. Some of the active channels are #general, #dreams, #comms, #stages-djs-musicians, … and new channels pop up every day. If you don't know where to ask, try #general.
