Thank you very much.  I added to my .gnus

(defun innout ()
  "Enter and exit every group, so that any articles that
   have been adaptive-scored low enough to have a 'Y' mark 
   won't be there when I enter manually, plus the article
   count will reflect the # of articles I actually might
   want to read."
  (interactive)
  (dolist (group gnus-newsrc-alist)  ; loop over all groups
    (when (and 
	   ;; Only apply to NNTP groups (only ones which do scoring)
	   (not (string-match "nnfolder\\|nndraft\\|dummy\\.group" (gnus-info-group group)))
	   ;; Is this group really subscribed?
	   (< (gnus-group-level (gnus-info-group group)) 5)
	   ;; Are there any unread messages?
	   (> (gnus-group-unread (gnus-info-group group)) 0)
)
      ;; Enter the group (must create the summary buffer or else
      ;; on exit the counts aren't updated
      (gnus-summary-read-group (gnus-info-group group) nil t nil nil)
      ;; and exit
      (gnus-summary-exit)
)))

Then I call innout from the *Group* buffer.  But the processing stops at the
first group that becomes completely empty with the error message "Wrong type
argument: stringp, nil".  What's going wrong?

Tschoe,
Torsten.
