The list of open positions, incumbents who are likely to seek another term, and the specifications of desired expertise have been posted to the NomCom 2022 pages at https://datatracker.ietf.org/nomcom/2022/ The IETF LLC Board is still a draft, and might be updated by September. Given the compressed timetable, I am posting all of them now. And speaking of timetable, I have not yet posted the detailed timetable, but will do so in a few days.
