Hello Linux Plumbers community!
All Microconferences have now been accepted. Please go ahead and take a look at them and if you find something you would like to discuss, please submit a contribution. To do so, go to the Call for Proposals page, select the Submit new abstract button, add your discussion topic and submit. Make sure to select the proper Microconference in the Track field.
It is also a good idea to read the blog about The Ideal Microconference Topic Submission to understand what is expected of a microconference topic.
