I've sent them all an email. Let's see what they say.

We still have the issue of the initial copyright line in the packages and guix translation. Some are to ludo, and it's easy to change. Some are to the FSF, and I'm not suse how we can change that. Should we ask them to allow the change? The rest is correctly attributed to the guix authors, but with different years.

send something to the translators alias?

So aside from Julien and me that’s,
(from the French PO file) Simon Tournier,
(from the German PO file) Mario Blättermann, Jonathan Brielmaier,
(from the Russian PO file) znavko, Pavlo Marianov, Adam,
(for Spanish) Miguel, (for Chinese) Meiyo Peng, and, I
wonder, have Ali Reza Hayati and Amin Bandali been working on the
manual already; are they listed as part of the guix-i18n@gnu.org?
They had asked how they could help with translating on
