Danke schön! Do you have entity–relationship model/digaram for the DB? I have tried to translate/change "car groups names" and it was little bit confusing. Default cars has ClassTextID as number and later reference in Texte table for translation But all custom/addon cars has group names directly in ClassTextID? If I want to create new group "Italian" and put there all Italian cars should I change ClassTextID to "Italian"?
