Using table copy for helping with Multi language possibilities has its pro's but also con's !!!
WHEN using the table copy on a existing site (example: it always did run on English) the copy creates copies of english into the language of your choice.
From the point you executed that 'command', each language will work and act as a standalone 'site'.
Meaning: any change on text position content etc.. will ONLY be visible IN that set language.
Creating a menu in (eg) German, does not provide the same menu in English or alike. So if a need for the same menu occurs in English, you will have to create it in English too + position
Please keep this in mind!!!
Good luck, and please go to next steps > Next tutorial in line
