Hello all,
the new CC-BY-SA site terms for Wikimedia wikis are ready to be translated through the WikimediaMessages extension:
http://www.mediawiki.org/wiki/Special:Code/MediaWiki/52361
The messages are wikimedia-copyright, wikimedia-copyrightwarning, and wikimedia-editpage-tos-summary.I've contacted Siebrand and Gerard from TranslateWiki and we hope they can be made available through the translatewiki.net interface soon.
We anticipate pushing these to Wikimedia wikis as early as Monday, June 29, if at all possible. At that time, all eligible wikis will show the new message; English messages will be shown if no translation is available by then.
These are very important legal messages, so to the extent that you can double-check the translations, please do so. They need to be translated literally, and the terms of use URL needs to point to the Wikimedia Foundation copy. If you don't feel confident to translate them, please leave the English version in place for now. Note that these messages _only_ apply to Wikimedia sites; they won't be shown in any other MediaWiki installation.

Thanks for all help! :-) Erik
