Hi Will, Josh, Julien, and Bill, Our MC has been formally accepted: https://www.linuxplumbersconf.org/blog/2021/index.php/2021/06/21/toolchains-and-kernel-microconference-accepted-into-2021-linux-plumbers-conference/ Would you mind please submitting a formal talk proposal at: https://www.linuxplumbersconf.org/event/11/abstracts/ In the bottom right, click "Submit new proposal" then make sure to select "Toolchains and Kernel" under the Track dropdown. The Content field will be what's shown to attendees. We'd like to close our CFP by August 14th, 2021. -- Thanks, ~Nick Desaulniers
