For hiding that text:
CODE
<style>.orangetext15 {display:none;visibility:hidden;} </style>
I doubt this will totally remove the Extended Network, but it might make it smaller:
CODE
<style type="text/css">
table table table td {vertical-align:top;}
span.blacktext12 {
visibility:hidden;
background-color:transparent;
font-size:0px; letter-spacing:-0.5px;
width:0px; height:0px; display:block;}
span.blacktext12 img {display:none;}
</style>
