From website:
The Gongfarmer’s Almanac (GFA) is a Dungeon Crawl Classics (DCC) and Mutant Crawl Classics (MCC) fanzine that also supports the many other flavors of DCC and MCC-compatible material.
Community created and funded
The Gongfarmer’s Almanac is produced by volunteers ranging from the first-time contributor to many names you’ll recognize as writers and artists from Goodman Game’s official releases. Volunteers participate in many ways, including project management, forum moderation, writing, artwork, cartography, editing, layout, proofing, and working with printers, shipping companies, and print-on-demand and PDF download distribution venues in order to make the whole project happen.
The initial publication is a series of approximately six to eight 48-56 page zines that are printed and distributed at Gen Con each year. Funding usually covers about 100 copies of each zine (so 600-800 individual copies!) and is obtained through individual donations. 100% of all donations goes towards actual printing and shipping costs.
After Gen Con, free PDF copies of each zine, along with a compiled volume of all zines, is made available for free on DriveThruRPG.
