If you fulfilled your profile correctly you must have marked your language preferences and clicked the box of notifications. When there's a request that matches your preferences (made by another user), an email will be sent to you and you can do the translation, OK?
By the way...looking at your profile I noticed that you forgot to click "yes" in the box of notifications. I did it now. Besides your preferences are confusing
You stated that you can only read Italian, but your preference of translation is from Spanish into English. Can you explain exactly what languages you really master and are able to translate?
I don't mark other language other italian becose I dont' speak more 75% english or spanish, but I'm able to translate when is request just the significate. Anyway, tank you for everithing.
