I emailed them to say I hadn't got their promised e-mail and got response with the missing document.... but it came from Thierry Rivet's private email so I guess something went a bit
poire-shaped in their automated system.
The document is almost the same as the previous attachment from when I'd only done 3 out of the 4 qualifiers - just the frame number added at the top.
If you've got the prior edition of the previous 'Accusé de Reception' a print of that + a print from the web page that 'ought' to be enough.
