I don't know if this feature already exists but I took the time to create an RSS manager.

When you want to enable RSS on a list or a Document Library you need to go to the list itself. This is not a hard job to do when you don't have many lists or libraries. With this feature you can manage this by just opening a page from the site settings.

You can download the RssManager package by clicking here.

Walkthrough time J.

1. Install the feature using following command line statements

   stsadm -o addsolution -filename "C:\RssManager.wsp"
   

   stsadm -o deploysolution -immediate -allowgacdeployment -name RssManager.wsp
   

   stsadm -o activatefeature -filename rssmanager\feature.xml –url "url of your site"

2. Create a new Site based on the Team Site Template
3. Go to the settings page by clicking on "Site Actions" and "Site Settings"
4. On the page click "RSS Manager"



5. Once you are on the page you can mark a checkbox to enable RSS on a list or uncheck to disable RSS on the list or library

Yet another feature that will make your SharePoint life better.
