Hello the list, The good news is that it is therefore of course already possible NOW to use Org inside Gnus and that everyone can use the export into html for a very clean scientific correspondence.
Many thanks to Carsten Dominik, to Bastien Guerry, to Eric Schulte and Dan Davidson, and to all this great team of Org. Forgive me if I cannot quote all the names. Best wishes, and happy new year again ! Jo.
