Re: Chairman pro tem

[Jon Bosak <Jon.Bosak@eng.sun.com>]

RROR says that you can appoint someone to take over the chair
of a meeting that you have to leave early but explicitly prohibits
you from appointing someone to act as chair in a meeting that you
cannot attend at all.  In the latter case, the committee itself
has to select a chair pro tem. in your absence.
