i have grouped a number of newsgroups and hardly look at the group. Today, I opened the group and there were over 1,400,000 messages. I was unable to delete any messages from this large collection of messages. I selected some and right clicked and selected delete messages. I got the "OK" box, checked OK, it went away, but the messages remained. I had to go to each newsgroup separately and delete messages to reduce the size.
Also, many of the messages were from posters who I have indicated to delete all. I wonder if Newsbin could just delete those messages as it encounters them, rather than my having to delete them each time I download new messages.
