Thread:Help talk:Extension:Translate/Translate Linktext of a Wikilink transcluded from a template/reply

As Help:Extension:Translate/Page_translation_administration says, you can't call translatable templates directly, but only their languages subpages. This is usually done with templates like TNT or m:Template:Translatable template (the latter uses lua). Maybe in a distant future Translate will support this use case natively.
