Keeping your translation up-to-date is the only thing you have to do after the language is created, modified, tested and published on SVN. The advised frequency of languages updates is different, as it depends on a speed of the Drake CMS development process, but usually it should be updated at least 1 time every month. English language resources are sometimes edited for improvements, fixes and/or additions. If you are a simple user you should submit troubles related to the language files as patches, if you are the official project translator you should keep track the changes of SVN logs and update files using the Repair option available in the Language Manager. Example procedure for updating your language files is described below:
https://drakecms.svn.sourceforge.net/svnroot/drakecms/trunk/lang/en/and directory xx to path:
https://drakecms.svn.sourceforge.net/svnroot/drakecms/i18n/language/lang/xx/
Remember that you ARE NOT ALLOWED as a translator to commit changes into the trunk path:
https://drakecms.svn.sourceforge.net/svnroot/drakecms/trunk/
So, for example, the following path is WRONG, because you would overwrite the English language resources:
https://drakecms.svn.sourceforge.net/svnroot/drakecms/trunk/lang/en
