Translations multiply the impact that Elgg can have by making it accessible to a larger percentage of the world.
The community will always be indebted to those of you who work hard to provide high quality translations for Elgg's UI and docs.
All translation for the Elgg project is organized through Transifex.

Plugin authors are encouraged to coordinate translations via Transifex as well so the whole community can be unified and make it really easy for translators to contribute to any plugin in the Elgg ecosystem.
