Sorry, don’t know a better way to communicate to the host, but does an rpg need to have a kickstarter in order to join this game jam or publish their material? I design as a hobby and intend to release a one-page rpg soon, so I was wondering if I might be able to include my product.
I'm afraid that this Jam is just for ZineQuest projects so if you're not running a KS for your game it wouldn't be applicable. I'd recommend keeping an eye out for upcoming jams, there tend to be a fair number that would suit one page RPGs.
