Thread:Support/Problems with the use of GRAMMAR/reply

Well, message previews are meaningless anyway, since they don't reflect the reality and I would just disable the previews altogether (rendering the text as-is) if it was easy to do so.

Now what comes to translated pages, they should indeed be rendered with the target language of the translation. If this is not the case, it is a bug that I need to investigate.

What comes to the third point (disregarding the language of the message), that is a issue in MediaWiki itself, and more specifically a very hard one to fix.
