‘Only Pages in Feed’ is a little plugin that modifies WordPress RSS feed to exclude all ‘Post’ types and show only ‘Pages’ in it. So if you are using WordPress as a CMS and want only Pages to appear in your site feed, this plugin is for you.
The plugin needs no configuration. Just activate it, and you are good to go. Deactivating the plugin restores RSS feeds to their default state.

Only Pages in Feed

Remove all blog posts from site's RSS feeds, leaving only Pages.

It adds extra option fields to the user profile page where user can select the categories he wants to exclude from the site. You can allow excluding from the “Home page”, “Archive pages (excluding category archives)” or “Feeds” and also you can set which categories can users select for excluding. You will find all these setting on “My Category Excluder Settings” page in your admin panel.
It is really easy to use. User just selects the categories he wants to exclude on the “Your Profile” page in “Exclude these categories from the site” section and hits the “Update Profile” button.
I am open to suggestions to improve the plugin !

My Category Excluder

This plugin allows your registered users to exclude some categories from the queries on your site.
