Where did you get that code from? Anyway, do the same as I posted above, but change the style a bit. So, to make the usernames of a certain usergroup(s) bold & red, you would use:

Left box:

<span style="font-weight:bold;color:red;">

Right box:

</span>

Also, if you want it to say "Administrator" (or whatever) when you hover over a username of the usergroup with that markup, just change:

<span style="font-weight:bold;color:red;">

To this:

<span style="font-weight:bold;color:red;" title="Administrator">
