These are the old JEvents1.4.3 translation files. They may prove useful in creating a new translation for JEvents 1.5.
If you are able to create and maintain a translation for JEvents and are accepted as an official translator then you may be elligible for free membership of the JEvents club. Translators who maintain the official JEvents translation together with the translations of the JEvents club addons are eligible for free Contributor status (which is equivalent to Gold Membership) for the period that they continue to maintain the translations.
Please check in the translations forum before starting work on a new translation in case another translator is already working on the project.
