1790This will be used when doing followups and posts.

1792This is primarily useful in mail groups that represent closed
1793mailing lists--mailing lists where it's expected that everybody that
1794writes to the mailing list is subscribed to it. Since using this
1795parameter ensures that the mail only goes to the mailing list itself,
1796it means that members won't receive two copies of your followups.

1798Using `to-address' will actually work whether the group is foreign or
1799not. Let's say there's a group on the server that is called
1800`fa.4ad-l'. This is a real newsgroup, but the server has gotten the
1801articles from a mail-to-news gateway. Posting directly to this group
1802is therefore impossible--you have to send mail to the mailing list
1803address instead.

3058 summary specifier.
3059
eec82323
LMI		 3060The %U (status), %R (replied) and %z (zcore) specs have to be handled
3061with care. For reasons of efficiency, Gnus will compute what column
3062these characters will end up in, and \"hard-code\" that. This means that
65a32076 3063it is invalid to have these specs after a variable-length spec. Well,
eec82323
LMI		 3064you might not be arrested, but your summary buffer will look strange,
3065which is bad enough.
3066
23f87bed 3067The smart choice is to have these specs as far to the left as
eec82323
LMI		 3068possible.

MB		 3070This restriction may disappear in later versions of Gnus.

3072General format specifiers can also be used.
