[TYPO3-english] Correct use of tablenames field in mm tables

[Guillermo R. Oramas J.]

Hi Dmitry.

Thank you for the answers.

Could you explain a bit in depth this?:

>You can do it like this but it would be better to have separate mm tables in this case. You have three tables that you need to relate. That is best done through two separate tables.

And this?:

> Depends on your TCA configuration.
