<table width="100%" cellspacing="0" cellpadding="10" border="0">
   <tr>
      <td>
            <b><Actinic:Variable Name="AboutUsLabel"/></b>

            	<actinic:block php="true">
		// extract and obfuscate email address

		// now look for Email&#58; YourName &#91;at&#93; YourCompanyEmail &#91;dot&#93; com<br />
		if ( preg_match('/(.*Email&#58; )(.*?) &#91;at&#93; (.*?)(<br.*$)/', $aboutustext, $emailbits) )
			{

			$domain = str_replace(' &#91;dot&#93; ','&#46;',$emailbits[3]);		// fix any [dot]
			echo $emailbits[1];
			echo "<script type=\"text/javascript\">";
			echo "document.write('$ename' + String.fromCharCode(60 + 4) + '$domain');";
			echo "</script>"; 
			echo $emailbits[4];
			}
		else
			{
			echo $aboutustext;
			}
            	</actinic:block>
			
            </span>
