Sorry for the delay guys, but it was a busy week with the Transifex 0.5 Release.
Well, from where I can see, we could encourage people from the L10N group to join the NDN group. It would reduce delays as cited in another reply.
AFAIK we already have a set of people for the set of languages chosen, as we can see here[1]. Those people should have in mind that if they can't do the work for a specific news/period, they
could/must try contact theirs local Fedora main list (i.e fedora-trans-pt_br) asking someone to do the work.
What I mean is that IMHO the NDN more or less seems to be a selected group of people from the L10N group, with some more 'responsibilities', as focus in marketing, for example. So we are already working together more or less.
BTW if the NDN team wants to send an email for the fedora-trans-list once in a while announcing any topic/news to be translated, as an encouragement for other languages to start doing it, I can't see anything against it.
Just let me know if I misunderstood something. :)
