How do I add a drop shadow to the body of all my post's?

By the way, your theme is outstanding! I can't turn off my computer...it's an absolute blast to work with!

There are various ways to do this, probably with Javascript. Look for something that works with jQuery as that is already included in the theme. You will probably have to include Javascript in the head and in the body and also reference the container that is supposed to get the shadow which would be div.post-bodycopy
