We are starting to send out invitations in 5 hours. The process of expanding the list further and sending more invitations will happen in parallel.
Update on task: in-progress.
List of speakers gets updated at http://wikiworkshop.org/2018/#speakers as we hear back from them. We expect this task to continue in the next 1-1.5 month.
With Cong Yu accepting, we're done. The list will be updated with his name at http://wikiworkshop.org/2018/#speakers (in the next day or so). We may invite one more person if it works with the schedule, otherwise, this task is done. :)
