Welsh translation – A very old translation for v2.1 exists in the SVN repository http://svn.automattic.com/wordpress-i18n/cy/trunk/messages/

A new up-to-date translation for 3.0+ was created by another team, but they have only provided it on their own site here http://www.meddal.com/meddal/?page_id=103
(or Google translate it!)

There is a zip file on that page to download.

Can anyone help in getting this file updated in SVN?

thanks
