(Conferences): Added a reference to ``Recipients of comments'' under

	the explanation of rd-prot.
(Conference Status Types): Document super-conf properly.  It has two
	different uses.  (Bug 310).
(set-permitted-submitters): Document what it means when
	``permitted-submitters'' is zero, and that that setting is the
	default.
(set-super-conf): Added a reference to ``Conference Status Types''.
(The User Area): Spelling error fixed.
(Recipients of comments): Simplified the rules for super-conf.  A
	setting of 0 no longer means anything.  The previous meaning
	wasn't implemented.
