Pat, I've been whirling with Wordpress for many years now, and whilst it's a fine CMS and small- to medium-sized web design tool, it sucks as a links database for all sorts of reasons, not least that it ditched the LInks library in v2.8 or so. Indeed, my hope is that I might be able to write a WP plugin to remedy this lack.
