WordPress MU

Hello to all !

I have just set up a website using wordpress mu.
Everything works nicely !
But i have a little problem while customising my sidebar...

I wanted the sidebar to be placed at the right of the page.
But now it is in the middle.

I searched for CSS proprieties in the style.css but could not find any....

Please have a look at one of my blogs : http://lerestedumonde.com/blogs/crashtest/
(for example)

I would like the search bar and the name "Patrice Jamet" to be on the right of the page.

Could any one help me?

Merry christmas from france.

Thanks.

The location of the side bars is done through the page structure define in page.php and other files in each specific theme folder.
