Not a real worry on most of my systems but I'm curious: Eric> 1. what function does this buffer have in gnus? Eric> 2. can this be pruned back (manually or otherwise)? I think this should help: gnus-keep-backlog is a variable defined in `gnus.el'. Its value is 20 You can customize this variable. Probably introduced at or before Emacs version 19.32. Documentation: If non-nil, Gnus will keep read articles for later re-retrieval. If it is a number N, then Gnus will only keep the last N articles read. If it is neither nil nor a number, Gnus will keep all read articles. This is not a good idea. That=CA=BCs definitely a doc-string written by Lars :-) There=CA=BCs also: gnus-backlog-shutdown is an interactive compiled Lisp function in `gnus-bcklg.el'. (gnus-backlog-shutdown) Clear all backlog variables and buffers. Robert
