I know, that it's possible to use 2 languages in XOOPS. So if user selects first language, all the menu will be displayed in this language. But is it possible to display other info (such as news, FAQ and other) into this language too? For example, i write news: "XOOPS version 5.0 released yesterday" and write the same news in other language. How to make, that if user selects other language, he can see other info in this language? Any ideas, comments are highly welcome.

This is possible, but it is a rather huge project.
