Adding a Bit of Workflow to WordPress

As much as I love WordPress, one of the areas it really lacks is workflow. There are three basic statuses for posts (draft, pending review and published), but there’s very little difference between “draft” status and “pending review.” When a post is saved as “Pending for review”, nothing happens automatically. No email messages are dispatched to any of the site’s editors or administrators, no special, obvious flags fly within the admin area, etc. It might as well just be a “draft” for all intents and purposes. The idea behind creating the “pending review” status was to allow editors and administrators to tell the difference between an in-progress draft and a draft that was ready to be published, but that seems to be about it.
