Ah, I see (I rarely see nnml's server, so I didn't think of it).

Hmm.  I've ever faced it in the past, though I don't recall how
they were made.  But this should be why the server buffer list
those four.

It will do, but you'll need to run
`M-x nnml-generate-nov-databases-directory RET DIR_NAME RET'
after restoring the articles in the *new* stéphane group.
Instead, doing `B c' or `B m' in the summary buffer seems better.
As for deleting those duplicate groups, I'm not sure `G DEL' does
work as expected, though (you might have to edit manually active,
and .newsrc.eld :<).

Oh, that's too bad.

Anyway I'd like to know what happens after re-creating those groups.
Good luck.
