Hi,
I did a quick web search and found this link:

  http://support.nabble.com/Downsizing-Nabble-td7609715.html

The poster mentions that they are not doing mailing-list archives any more,
just forums, so I guess that's what we had(?).  No hope of getting it back if so.

I found this link first, for another org that got shut down (points to the above):

  https://www.osgeo.org/foundation-news/osgeo-nabble-forum-is-shutting-down/

Strange that nabble.com itself seems not to have any mention!
