Module namespace - translation on Bulgarian

I'd like to see confirmation from someone who's actually done translations into Bulgarian. Kolega2357 has a self-assessed skill level of 1 on a scale from 1-4, which isn't enough for me. See active translator(s) for Bulgarian.

It's OK, we can use it as it was suggested. Am I missing something, but why we need to translate custom namespaces or this one is part of MediaWiki/Translatewiki?

Thanks for the input!

User Bogorm helped me for Bulgarian translation. [1], [2] See here.
