Is it possible to change names and stuff like 'discussions' within dashboard?

Eg; in 'Pligg' they have a feature called language where you could change those thing.

I'm afraid it is not possible.
There is a way to redirect the names in your url by htaccess.

You can change all the language settings using locales like this.
