ceramic.wiki is an independently run reference with real ongoing costs: server hosting, the domain name, and the services the Events and Opportunities boards depend on. The site carries no ads and no paywall, and is maintained on a volunteer basis rather than funding any paid staff.
A donation option is planned but not yet set up — this page will be updated with a real way to contribute once one exists, rather than link to something that isn't there yet. Anyone who wants to support the site sooner than that is welcome to reach out via the contact page.
