Yes, cacheing for newgroups is one way and that is what I asked
about. However in reality I copy *mail* messages to different groups
for various reasons too.  And in that case the cache method is
redundant and wasteful.

I'd still like a way for gnus to let me know when I try to copy the
same message to a group where that message already resides.  Or better
still:

Have gnus let me know there are dups, and ask me if I want gnus to
sort them out before `B c' ing them.

Is there already functionality that covers this or comes close?
