Root Page information

I just joined wordpress.org and I’m tinkering around with a blog.
I was trying to change the word “Pages” to something else.

This is the link to my site
http://handimation.wordpress.com/

The word “Pages” appears just below the search box.

Where do I administer a change of this word to something else?

Example: I want it to read “The Project”

Thanks
