Welsh

Although I don't speak Welsh I would like to get a collection of Welsh translations together for Drupal.

I thought I would play around with the translation modules on my blog last night and installed french, spanish and welsh. French and spanish both had a few hundred core translations, welsh had none and there are no downloadable welsh translations I can see.

Are there any?
Can we do somthing about it?
Do I need to learn welsh?

Help!
