It would be nice to have an additional field for Artisteer slogan-text in the Site Settings (an optional field) for skins from Artisteer.
All Altisteer templates have this by default including the 2 new Artisteer templates in version 2.3.3.9.
The new Artisteer markup is in the skin layout.master around line 65-70.
<div id="slogan-text" class="art-Logo-text">
Living The Dream</div>
See my Home Page to see my Slogan Text. "Living The Dream"

If the slogan-text is left empty then no slogan text would appear.
Just thinking out load Joe.
