Wikiblame is able to quickly find the authors of good, questionable or even dangerous (e.g. copyrighted) passages of a page in a Wikimedia wiki. This could be handy for asking users about their contributions or in order to fulfil the demands of GFDL or CC-BY-SA when copying parts of a page. (released under an unknown license).
It is possible to translate Wikiblame on translatewiki.net. Siebrand coordinates the localisation of Wikiblame. Reports about Wikiblame should be made in its SourceForge tracker or on Support (spelling issues only). Translations for WikiBlame are committed to the source code irregularly; usually every two to four weeks.
