Changing the style of posts?

First day using the aqua-soft skin

It has been going awesome, but i have one question:

How can i make my posts on my site look more like the posts on Aqua-soft.org

Turn on legacy postbit in the admin settings.

Can you please be more precise! Where in admin settings?

Admincp -> vBulletin Options -> Style & Language Settings -> Use Legacy (Vertical)...

Thank You so much!!!
