How TF do I exchange blogs???

I've had this blog for a little bit over a year now, and I STILL HAVE NO EFFIN' IDEA HOW TO EXCHANGE LINKS!! Help a brotha out, because I get emails asking for me to exchange links with blah blah blah but I have no idea how to do it. So, enjoy the pics, but someone puh-leeeezzee answer this damn question for me!
