This is an OpenPGP/MIME signed message (RFC 2440 and 3156)
But I don't think that imposing a code of conduct by High Command from
the board is healthy, and I don't think it will help its adoption.
Well, the board is no high court which comes from heavon but elected
from all members of the GNOME Foundation. All members of the gnome
community (at least anyone who has constributed something non-trivial)
can join the foundation and can control the board.
So who should make this conduct official if not the board if as you say
the vast majority agrees?
