DjZoNe

This plugin was born because there was a no other real alternative to enable content sparationd and some CMS like functionalities in WordPress. 
The main goal was, to enhance WordPress’s functionalities, to hide some unwanted categories, from defined parts of the blog.
Today, ACE can override your search results, your RSS feed listing, your category listing, your recent post, and recent post widgets and also your entry page, or even hide whole categories of posts from web crawlers if you want to. 
This is great, for SEO reasons, for content separation, for grouping information, and handle them as real sub pages.
