Forum:How to change the color of my username in the WikiActivity?

I'm an admin at the One Tree Hill Wiki, and I noticed that in the WikiActivity, Caiite's name was in gold/yellow which implies that she is also a sysop. How would I go about making that change to my name?  Love and Lust  04:29, September 3, 2012 (UTC)
 * This can be with basic css on your wikia css:


 * This will change the link color to your userpage on any page, not just recent changes. 04:47, September 3, 2012 (UTC)


 * Okay, but how do I get to the CSS? Is it through a MediaWiki link? If so, could you give me the page name? I'm new to CSS and JS coding.  Love and Lust  04:56, September 3, 2012 (UTC)
