I am currently using the latest version of WP and Atahualpa and am having trouble getting the page menu bar to center correctly.

Per other threads, I am using this code to add some spacing to the menu bar.

ul.rMenu li {
margin-right: 40px;
}
/*reset for submenus*/
ul.rMenu li ul li {
margin-right: 0;
}

The problem is that this throws the bar off center.

How can I maintain the spacing in between while still centering the whole page menu bar?

You can see the page here. (ignore the temporary logo)

The center of "FORUMS" should be between the two banner ads for it to be centered.

see ato->Style & edit HEADER AREA->Style & edit HEADER AREA: %page-center

I already am using that. The extra width I placed between the menu bar options is throwing the whole bar off center and I would like to know how to maintain that spacing.

you should try setting a left margin also

Ah, such a simple answer yet the perfect solution. Thank you
