DOCBOOK-APPS: Suppress those "@"s in flat website?

I am using the 'flat' website DTD to create a rather nice looking site if I
don't say so myself (http://numerologypro.com -- comments welcome). <g>

Is it possible suppress the trailing 'commercial at's that mark the current
page in the nav bars?

I am getting feedback from members of the general public, God bless 'em,
that they are a tad taken aback by this symbol. They don't know what it is,
and think there's something wrong with their computer...
