As soon as you have upgraded this Jimdo Website to a Pro or Business version, you can copy finished pages in the navigation and translate them.
If you are not sure how to do this, you can have a look in the Jimde help section in the right hand menu.
And of course you can use multiple languages.
If you don't want a language selection, you can change the name of the top page (here it is De) to Home, transfer the subpages to the first level by using the
little arrows and simply delete the page EN.
