We have set up a forum dedicated to RIOT, which you can now enjoy at https://forum.riot-os.org/
This process follows the conclusions of our recent survey on this topic 1. The forum is a Discourse instance.
Migration planned by end of 2020: Please be informed that we plan to migrate all email discussions to the forum, gradually, over the next ~4 weeks.
We thus invite you to register to the forum soon, and to post your next messages there, instead of on this mailing list.
Email interaction as of 2021: We leave noone behind: if you have a strong preference for email interaction still, simple settings in Discourse enable posting and receiving forum messages via email 2.
Looking forward to see you on the Forum!
