+@itemx mboxstatus
+Download status mbox. The use of either symbol depends on the actual
+Debbugs server configuration. For @code{"gnu.org"}, use the former;
+for @code{"debian.org} - the latter.
+@end table
+
+@var{filename}, if non-@code{nil}, is the name of the file to store
+mbox. If @var{filename} is @code{nil}, the downloaded mbox is
+inserted into the current buffer.
+
+Note, that mbox downloading will work only if the
+@code{:bugreport-url} field of the @code{debbugs-servers} variable is
+specified (@pxref{Configuration}).

+@node Requesting user tags
+@chapter Requesting user tags
+
+A user tag is a string, a user has assigned to one or several bugs.
+The user is identified by an email address. The port @code{"gnu.org"}
+uses also package names as user identification.
+
+@defun debbugs-get-usertag &rest query
+Return a list of bug numbers which match @var{query}.
+
+@var{query} is a sequence of keyword-value pairs where the values are
+strings, i.e. :KEYWORD ``VALUE'' [:KEYWORD ``VALUE'']*
+
+Valid keywords are:
+
+@table @code
+@item :user
+The value is the name of the package a bug belongs to, like
+@code{"emacs"}, @code{"coreutils"}, or @code{"tramp"}. It can also be
+an email address of a user who has applied a user tag. The special
+email address @code{"me"} is used as pattern, replaced with
+@code{user-mail-address}. There must be at least one such entry; it
+is recommended to have exactly one.
+
+@item :tag
+A string applied as user tag. Often, it is a subproduct
+identification, like @code{"cedet"} or @code{"tramp"} for the package
+@code{"emacs"}.
