I wrestled with a way to customize the content, not just the formatting, of the Support page header so customers could get back to my main web site. I could not find an existing topic on this, so I thought I'd share what I ended up with.
/* This gets the first row from the Table Header div section where your logo and Support link are by default */ var firstRow=document.getElementById("table_header").rows;
/* This specifies the position of the new cell in the current row. 1 will put your item after the logo. The value of -1 can also be used; which results in that the new cell will be inserted at the last position.*/ var firstCell=firstRow.insertCell(1); firstCell.innerHTML="<a href=\"http://www.denvog.com/about\">About</a>";
