If people want to create banners for their larps Diatribe is happy to display them. Currently running larps like Pirates, Nightmare Circle, Ravenholme, Quest Waikato, One World by Night, Stargate, etc could benefit from this. I think the current Diatribe policy is to advertise any NZ larp-related thing for free.
If working with graphics doesn’t appeal, put your hand up and someone will probably volunteer to make one for you.
