I am not an experienced Magento user but a client has asked me to provide them with translations for their whole site.
1) The "Translation overview" page gives a few hints but not quite enough to make sure the dictionary will contain all the UI and shop strings.
2) The current store/site is in French and must be localized to English. According to Adding a Language, that seems to mean that the English original "version" was disabled and the French version is the only one displayed. Is that correct ? Is there a possibility that the English has to be added (for ex. if the French was originally set as default at the site creation) ?
3) Once the English is added (or activated), how do I make sure that the .csv translation dictionary contains *all* the site/store strings ?
