If you configured your system as a translation server you can share your translations by exporting them to a language pack.

To export a language pack, go to Administration > System configuration > Languages > Language administration and press the Export languages packages button. Select the languages you want to export as a language pack and finish by pressing the appropriate button. The system creates the language pack for you and starts the download to your local hard drive. You can now share this language pack with others and import it to another system.
