First of all mod supports user default language. It is set in registration form and can be changed in User CP. So if user has set his default language, then he does nothing... Just writes posts in his language, and vBET takes care about everything. In such case - when user has set default language it is assumed that whole post (including title) is written in his default language. It will be configurable soon, but at his moment there is simple assumption: if user has set default language and it is different than forum default language, then each his message is in language which he choose as his default.

You can also create multi language messages, where only parts of message are in different languages. This is very easy - everything what you need to do it put text written in different language inside of lang BBCode. It takes one parameter which is the language code. I.e. if you want to write something in Polish, then BBCode looks like this lang=pl.
See whole example (spaces in BBCode added to avoid evaluation):
[ lang=pl]Przykład tekstu po polsku[ /lang]

This example (without spaces in BBCode) will give you such result:
Text automatically translated from: Polish to: English
Translated text
Example of text in Polish
Original text


There is also one more BBCode which works exactly as lang BBCode, but it's reserved for posts titles only. It is langtitle BBCode - it is used by vBET to automatically mark message of user which set theirs default language other than forum default language. It shouldn't be used manually, and if you want to use it such way, then remember to put whole message inside of lang BBCode using same language code as parameter in booth BBCodes (otherwise some parts of translated RSS channels can be not translated appropriately, but posts will be shown appropriately).

There is really one more BBCode, but it is not for translation - in fact it is to keep text not translated. If you want some text i post to be not translated, just simple out it inside of notranslate BBCode. It can be useful in case of some terms, or citation of some poems etc.

For example this text will never be translated. You can check it by clicking some translation flag - you will see this part will stay in original
