I've previously sold itch.io keys at PAX Aus and other events, and people are highly receptive to the idea of 'like Steam but for smaller games' - BUT, it'd be awesome to have a premade flyer as a PDF you can encourage devs to print and have at their booths, etc.

This'd be a good thing we could use to start the idea of a street team - folks who can help get more presence in geographical areas, etc.

I'd second that. I occasionally attend small game developer events and having some kind of flyers to distribute would be great

This is great! I'd like to help to spread them too, if this happens.
