Where do I put the code to get a profile layout? And how do I get there?

you can go here: http://www.subetahq.com/vgraphic.php?act=profiles to find a layout you like. it also has instructions on how to use the layout
or you can go to this one: http://www.subetalodge.org/graphics. for this one, basically click on the layout then copy the code provided into a blank section
