When in the administrative interface, choose the Links top-level menu item, then choose Add Link. The link form lets you choose which XFN properties you wish the link to have. When displaying the links on the site via any of the standard WordPress template tags, it will automatically format it with the appropriate tags in the rel attribute. (based on XFN Creator)
