Thread:Support/List of all system messages of translatewiki.net cannot be displayed/reply (4)

So I found the message in the Thanks extension by German Wikipedia system messages. And only because I found the message name on the help page for the Echo extension in German WP which I found by a link in an information banner. For the time stamp message I have the text only - the only text that could be true is this for MediaWiki:Centralauth-days-ago/de. But Centralauth is another extension.
