I frankly don't believe it matters a whole lot with DG-TREN. Since the only consultation was IPM, they don't put up (unless I'm mistaken) a page with contributions as with the Biofuels Consultation. They may acknowledge receipt. I sent the e-mails return receipt, but that should go to etg@eurotrib.com, which only Jérôme has access to. So should any response they make.
They're not going to take any notice of what we say anyway, we know that ;)
