I added two new WordPress plugins, which are WordPress Related Posts and WP-OpenID.
WordPress Related Posts automatically writes related links of your posts below the contents. Relation is determined by tags you add.
WP-OpenID, another plugin, enables OpenID when visitors post comments. In addition, you can use OpenID when you log in to Admin section.
For connecting admin users and OpenIDs, go to “Your Identity URLs” page at Profile (or Users) after logging in, then register your OpenID.
