The fundraiser just started today. You can support that fundraiser on this GoFundMe page. As of this moment, we're nearly to the first milestone, which will mean a perk opens up. And there are lots of other nifty S&F-related perks to become available as the donations rack up. Other perks might be announced later.
If you're at all interested in World SF and want to see more content on S&F related to that theme, please support the fundraiser!
