Try:
classic_stylesheet_big_avatar
and adjust the final selector:
div.avatar-label {
white-space:nowrap;
font-size:80%;
}
I found it by displaying at the HTML of the page you posted the URL for. That doesn't have 11 posts by Guru on it so I search for "Administrator" instead. That found::
<div class="avatar-label weak-color"><b>Administrator</b></div>
<div class="post-count1 avatar-label weak-color"></div>
So I then hunted for the CSS code for div.avatar-label which turned up a block of code earlier in the page, Then I searched for a macro that included that code.
(Actually, I followed a couple of other false leads before I did what I describe here!)
