Hello,
The chapters and thematic organizations are nominating people for the chapter-selected WMF Board seats. See https://meta.m.wikimedia.org/wiki/Affiliate-selected_Board_seats
The searches for an interim WMF ED and a long-term WMF ED have had few specifics published about them so far. I am anticipating that a current or former WMF senior manager will get the interim ED role, and that the Board will prioritize speed in making this selection. I anticipate little community involvement in that selection because of the need for speed.
For the selection process of the long-term ED, I hope that there will be meaningful opportunities for community participation.
