Putting on an event
All events at Matilda are organised through the collectives. Pick whichever group you think is most relevent to your event and talk to them about what you want to do, what you need etc..
If you're not sure who to talk to or where to go you can always send an email to the Matilda discussion list (you don't have to join it first). There is also an events blueprint which should be followed by people organising events.
