Thanks, everyone, for your kind words.
@Aaron Chan:
It's been a while since I made that change, but I believe this was the solution. Please let me know if this doesn't do the trick and I'll hunt check into it further.
In your template.css file (found in templates/rt_synapse_j15/css), starting around line 224 replace the original code with the code below:
#showcase {
overflow: hidden;
}
#showcase-padding {
padding-top: 5px;
}
#maincol {
padding: 40px 20px 60px 30px;
}
#leftcol,
#rightcol {
margin-left: -8px;
margin-right: -8px;
}
