you could edit the aboutus.php page the code for the address is:
<div class="block">
<h2>Address</h2>
<p><?php echo($WAGLOBAL_Address); ?></p>
<p><?php echo($WAGLOBAL_City); ?>, <?php echo($WAGLOBAL_State); ?> <?php echo($WAGLOBAL_Zip); ?></p>
<p><?php echo($WAGLOBAL_Country); ?></p>
</div>
you could remove any of the pieces from that code you did not want to have displayed.
