Zillow co-branding

Is there a way to add my username to Zillow links for the co-branding?

Just need to ‘”add the parameter “#{scrnnm=zillowscreenname}” to the end of any URL that links to Zillow, and substitute your Zillow account screen name for “zillowscreenname.”‘ http://www.zillow.com/cobrand/
