Join the Atreus mailing list to discuss your build process, layout design, crazy firmware hacks, or any questions you may have about the keyboard.
To join, send an email to firstname.lastname@example.org with "subscribe" in the subject, and follow the instructions in the reply you receive. HTML archives are available. Discussion from 2014 and 2015 took place on Librelist, but that service is no longer operational.
Other sites on which the Atreus is discussed include GeekHack, the Mechanical Keyboards subreddit, and Deskthority. In particular the original GeekHack thread about the Atreus continues to receive posts.
