@popeme

If all the channel popes leave the channel, then normally no one can
get moderator status without everyone leaving and rejoining. Instead,
if there are no popes on a channel, any channel member can type
@popeme and receive moderator status. Obviously, this only works for
one person, who must then give everyone else moderator status normally.

Usage:

@popeme foo (Tries to get moderator status on foo)
