How does this work as far as CNFS is concerned? If I create a buffer
"alt" (alt.binaries is always in a seperate buffer, in my case) and want
to expire alt.fan, for instance, after 1 day, will the news system somehow
be able to "reuse" teh expired space before it overwrites articles in
other, non-expire based groups?
