Checking translations

We are checking all changes in string translations in very easy way: our Estoanian team linguist (Marek Laane, JCA) is subscribed to et-cvs@openoffice.org mailing lists. When a commit is made he just writes his comments to the same list. We are using the same system in all projects, for projects without needed infrastructure (Firefox, Thunderbird) we use Google Groups with or without RSS feature for redirecting version-control-system commit messages, for projects with common mailing list for all changes (like openSUSE) I first automatically filter out et/po messages using my GMail account which deletes all other languages commits and redirects et/po commits to Google group. It's very easy to do because diffs of po-files are easy readable.
