Suggestion: Stream or Talk Page for Translation Documents or Categroies
Wiki has a Talk page for editors tabbed to every document. Gutenberg Proofreaders Project has a Forum link for every document.
Something like that or a sub-topic Translations stream for each language/category/document would be valuable to share idioms, insights and discussions with other translators.
Very happy to seeing Luis agree on this. I think it is crucial not only for improving the quality of translation (and for learning more from other translators' comments) but also to increase the community interaction on the site.
