It can be done, but the code changes I suggest below will disable the 190 wide social media slider that normally appears to the right of the leaderboard. If you decide you want to turn on the social media slider at some point in the future you will need to change the code back to the original version.
Locate these two lines in the Socrates style.css file:
Code:
.top728 { width:728px; height:90px; background-color:#FFFFFF; float:left; overflow:hidden;}
.side190 { width:220px; height:90px; float:right; overflow:hidden; }
And change them to this:
Code:
.top728 { width:728px; height:90px; background-color:#FFFFFF; float:none; overflow:hidden; margin-left:auto; margin-right:auto; text-align:center;}
.side190 { width:220px; height:90px; float:right; overflow:hidden; display:none;}
