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.
This is a 1 time method
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
