Admins & Bureaucrats Highlight

This code changes the color of the admins' and bureacrats' user names and makes them bolded. Although in the "Recent Wiki Activity" box on the side of the wiki they are only showed as bold. (You can also use this for any other user)

Implementation
Copy this into your wiki's MediaWiki:Wikia.css

a[href="/wiki/User:Admin's Username"] { color: #006600; font-weight:bold; !important; }

Then replace the "Admin's Username" with the admin's/bureaucrat's username. You can also change or remove the other values to change how the user's name appears.

Then repeat the code for each user's name you want to change the color of.
