If you look at the top of this page you'll see "Welcome,
calligirl". Directly under that (well, three lines under that) you'll see "My Mood:". Just click on that and a drop down of moods will appear. Just select one and click on it and it will appear on your page. You can change it by following the same directions and choosing a different mood.
