Unfortunately the groups.io settings would have been inherited
from the Yahoo group as part of the migration process.  The Yahoo
group was set up as a private group (as befits a family or commercial
discussion group), so the archives and files were never public.

I doubt that it is possible to retrospectively change that because
that would expose posts made when the group was private.

Agreed, in every respect groups.io is an improvement on
Yahoo and on traditional mailing lists like this one.

Eventually the blacksheep computer will fail - it's have been running
on borrowed time for years now!  We have been very lucky with it.

A solution would be to create a new group on groups.io with public
archives and files.  groups.io itself might last 10 years or so, but
the public archives will last indefinitely as a resource for
historians.
