This plugin makes WordPress more compatible with the XHTML Friends Network by publishing the XFN relationships of invisible links. Normally, WordPress only publishes the relationships assigned to visible links, so you can only show a relationship with people you want to link to in your sidebar. With XFN Friendlier, you can still be friends with people even if you donâ€™t show a link to them.
Download the plugin from here and copy it to your wp-content/plugins/ directory, activate, and youâ€™re done!
XFN Friendlier is currently numbered version 0.1, but itâ€™s so simple itâ€™s hard to imagine anything that could go wrong with it.
