Here is my help and others can also try too.
HIT BLOG
LOGIN OR SIGN UP (I used my user name crackednfragile, I was given a code but you might be able to pick your own and then I gave it a title "darkshadows"
YOU GET YOUR SITE
THEN YOU CLICK "PRESENTATION" AND SCROLL DOWN AND PICK. (right now it it was hard to pick the one I wanted because some of the pictures didn't show up on my browser. I just kept hitting the back key and retrying til I found one I liked.
I hope this helps!!!!
