What is the best method of implementation with regards to having multiple languages of the same website/content? Do I have to worry about dupe content issues? What about my database and files? I use a simple CMS....header/footer/index I am somewhat a noob so please explain thoroughly...thanks in advance.
You need to put more detail for people to help. If you use a DB for the content, then there will be an entry of the content for each languages.
