Thread:Translating talk:Flagged Revs extension/How do I go about fixing Polish translations?

I find some Polish translations (in particular, MediaWiki:Revreview-accuracy/pl) inadequate or inconsistent (MediaWiki:Revreview-depth-0/pl versus MediaWiki:Revreview-style-0/pl). Can I just fix them here or should I do anything special first? Editing them in a test wiki first does not seem to be an option; you need to have administrator rights to edit interface messages there.
