If you want to make you own translation of the client-side without waiting for the final version with you locale, here's a list of the files you need to change.Remember if you upgrade you installation all your translations are lost and you must do it all over again. My advice: keep a copy of your translated files somewhere else.* check all files inside /include/client most of what needs translation are here* class.forms.php and class.nav.php inside the /include folder - These are the menu bars and other stuff* Go to the Administration section / Pages and Forms - all these need translation.I think that's most of it.Hope I could help
