Why not just write the instructions on a page and all people can follow those instructions instead of each translator have to explain to another translator.
I dont think there are translators for all translations.
Some translations have not been updated for years.
On some pages it says "Warning: The author of this contribution does not provide support for it anymore." like on
https://www.phpbb.com/customise/db/tran ... onorifics/
It seem 25 out of 55 language packs are updated to 3.2.2.
Maybe instructions would help improve that.
I work on translating other software and alot of projects have a contribute page or similar page that could say how to download, translate, submit, update translations.
