Most large commercial online presences are offered in more than one language. The users love it, but until only recently, this would have given the developer untold problems. Any changes would have to be made on at least two pages. Often a page would be missed, a link would not be set, etc. TYPO3 allows you to create multilingual sites easily and in two different ways:
The multiple-tree concept
the one-tree-fits-all-languages concept.
Both of these versions warrant a closer look, because there is an interesting concept behind TYPO3's multilingual websites: If a page is called up in a language that has no translation, the page is displayed in the default language. Thus you do not have to be afraid of empty pages with missing translations.
How well TYPO3's multilingualism works can be confirmed by a glance at the back end. Every editor can choose his or her favorite language there. And you can create web pages using the same principle.
