Admin Forum:Changing the display name of my wiki

This is my wiki: http://he.elect.wikia.com/wiki/%D7%A2%D7%9E%D7%95%D7%93_%D7%A8%D7%90%D7%A9%D7%99

As you can see, it is in Hebrew, but the title on the top right is in English - "Elect Wiki". I would like to change that title  to Hebrew too.

How can I change the text of the title?
