Forum:User name color not working

I recently changed my username from 'Totalsolitude' to 'Utter solitude'. I am admin on two wikis, and on both I use css to change my username colour. When my name changed, I went into the css page and changed the code from:

a[href="/wiki/User:Totalsolitude"]{ color:purple !important; }

To:

a[href="/wiki/User:Utter solitude"]{ color:purple !important; }

I cleared my cache aaanndd.... nothing. 'Utter solitude' still shows in the standard color of the wiki, like regular users. What am I doing wrong? Advice would be much appreciated! :) Utter solitude 22:16, May 17, 2012 (UTC)
