Hi, this problem is getting worse and worse: whenever I visit nntp+Gmane:gmane.emacs.devel or nntp+Gmane:gmane.emacs.help (I used to read these groups a lot for years), even if there are only a few new messages, and even if I say "only download a few old messages", Gnus still downloads around 2 MB of data from the server each time.
Expiring the group does not help. Group catchup also doesn't change this. The only thing that does help is M-c (`gnus-group-clear-data') which clears all related group data completely, as far as I understand. But this is very radical - maybe I don't need a history of many years of activity, but I don't want to loose all of the recent data, too. Can anyone provide a better solution for this problem? TIA, Michael.
