This may be more of a process check, but:
The IESG has approved the creation of the working group. The
Secretariat will send a WG Action Announcement with copies to the
working group chairs.
Better to cc the WG mailing list. Chairs are on it.
The IESG has approved the modifications to the charter. Bert Wijnen
will send a revised charter to the Secretariat. The Secretariat will
send a WG Action: RECHARTER announcement with copies to the working
group chairs upon notification from Bert.
Same here.
