Ok, this is what I've done...
All default skin sets have the CDU search bar up top, to the right of the the organissimo forum logo. To get the search bar back into the white space beneath the member bar (like it was before), use the alternate skins under each color.
For instance, Org 2.1.3 Blue places the search bar in the logo strip, to the right of the organissimo logo. Org 2.1.3 Blue alt places it in the white space. It is the same for every color skin.
Enjoy!
