I'm playing around with my navigation a bit and can't figure out how to center the top (main?) navigation instead of how they are fixed to the left currently. I've tried playing around with extra.css, navigation.css, and the navigation template itself using html to no avail (Home, Forums, Suggestions, etc).
I also would like to get rid of the small 1px top border above the 'current page' tab and directly below the top user bar - when logged in you can see a small grey 1px border running along beneath the bar with Inbox, Alerts, and the Log Out option.
Any ideas would help me tremendously.
