Okay, I shouldn't be obnoxious and give credit where credit is due. I took the code from http://www.eckscheerleader.blogdrive.com/. It's a CSS thing (Cascading Style Sheets), and the dropcap class-thingee is this:
font: normal 60pt/0.8em Georgia,Helvetica, Verdana, Arial, sans-serif;
As I learn more and more about CSS, I can't believe I survived so long without it.
