Sachin,
glad to hear that want to help in the translation of dotLRN!
Try adding the locales that you need in the acs-lang/admin interface and just set the charsets to UTF8 for now, we can change them later. Let me know if there is anything that prevents you from starting your translations.
Sachin, could you post a complete list of all languages that you are planning to translate? Specifically, does it incluce Telugu? (I know some guys who might want to help out with that one)
