Hi there. Actually, you can't - it's not like here or MySpace where you add friends. It's just a straight blog. You can add links to your friend's sites though. If that's what you want to do, you can do that by editing your template and adding in the html.
I'm thinking that's not what you want to do, though? But if it is, let me know and I can be more specific.
