[sent to current Subversion translators as listed in COMMITTERS]
This is a proposal to use the Translation project for the Subversion translations, since most of the existing ones have not been kept up to date.
There are experienced teams for the languages that Subversion is currently translated into and many more. The risk for orphaned localisations will be lower since the teams deal with continuity themselves. Users will enjoy higher consistency in terms of vocabulary and style across software packages.
The details can be read at http://translationproject.org. Current Subversion translators who wish to continue their work would join their respective TP teams, where they would no doubt be more than welcome, with no obligation to take on more work but with the benefit of working in a larger team.
An alternative proposal would be to use the existing Pootle instance at <https://translate.apache.org/projects/Subversion/>. Either would be an improvement on the current situation. I'm personally more in favour of TP as it to me appears more organised and having translated a greater number of relevant software packages.
