Xen Wiki Update

Aron Giffis from HP has been helping me with the Xen Wiki and has created a great update to the Wiki to improve the css stylesheet. You can see his proposed update at http://userstyles.org/styles/8431. I am in the process of updating the stylesheets to implement this change permanently, but you can at least see the update in the mean time.
Thanks to Aron for his help on improving the Xen Wiki.
