Some people prefer to letterbox every second household and inform as such on the flyer to encourage interested persons to share their interest with their neighbor. Don't be too fancy or fussy with the design, keep it simple, black and white, keep it affordable. At the meetup ask people if they have I2P and if not offer, them basic instructions on how to setup the best way you know, with the version that you think is most secure.
