What's the process for getting a talk on the list? Looks like the space for it would be during the unconference? https://office.wikimedia.org/wiki/All_hands/2019/Conference_Schedule#Friday_Feb._1,_2019_-_Conference_Day_2_-_Bently_Reserve_(Wikimedia_Office_closed_until_3pm) (sorry for the long, ugly, and private url)
Looks like there will be time for lightning talk at All Hands:
Lightning talks that reach everybody (Thursday and Friday) are already full, as far as I can see.
The schedule is closed now, we can't take any new signups.
