Maybe, that I am asking too much, but my experience with mutt is that everything is possible -- one just has to know, what to put in .muttrc. So,
would it be possible to hide read messages in a newsgroups (using VVV patch for nntp on mutt 1.3.22.1i and listerver is local leafnode)? I mean, that it would be much better if there would be only unread messages in opened newsgroup. Sorry for my English, it's getting to late on me :-) Thanks for answer Matej Cepl
